Item 5.  Other Events.

On February 4, 1998, BroadBand Technologies, Inc. ("BBT") entered into several
agreements with Lucent Technologies, Inc. ("Lucent") that establish a new
nonexclusive relationship which replaces the exclusive relationship between BBT
and Lucent entered into in 1995 with respect to the SDBAS joint product.

The following description of agreements with Lucent are only summaries.
Investors are advised to read each agreement in their entirety to understand all
the terms of these agreements.

The new agreements between Lucent and BBT include a Settlement Agreement and
mutual releases by BroadBand and Lucent of all liabilities arising prior to
February 4, 1998. The Settlement Agreement terminates the SDV Supply Agreement
Contract No. LGC-A65-D between Lucent and BBT dated November 15, 1995, as
amended July 12, 1996 (the "Exclusive Agreement"), relating to the development
and sale of the joint BBT/Lucent SDBAS product. Pursuant to a new SDBAS Supply
Agreement BBT will continue to supply its FLX 2500 to Lucent. Under the
Settlement Agreement, BBT agrees to support Lucent's decisions with regard to
the marketing of SDBAS products and the appropriate transition to Lucent's
AnyMedia(TM) products. While Lucent will make all customer related decisions for
the joint SDBAS product, BBT is free to market its FLX-2500 product independent
of the joint SDBAS product either as a stand alone product or in conjunction
with the products of other digital loop carrier vendors. Substantial practical
impediments exist, however, to BBT selling its FLX-2500 product independent of
the SDBAS product. Under the Settlement Agreement, (i) BBT's expenses in
supporting Lucent other than ordinary expenses in fulfilling its obligations
under the SDBAS Supply Agreement are capped at $5.5 million in the aggregate;
(ii) Lucent cancelled BBT's obligation to pay Lucent $5 million in penalties
owed to Lucent under the Exclusive Agreement and (iii) Lucent cancelled BBT's
obligation to repay $6 million of hardware prepayments Lucent made to BBT under
the Exclusive Agreement.

On February 4, 1998, BBT and Lucent also entered into a Research and Development
Agreement (the "R & D Agreement"), for BBT to develop products for Lucent's new
AnyMedia digital loop carrier product. Under the R &D Agreement, Lucent has
committed to pay BBT at least $21 million payable in equal installments over a
three year period. BBT and Lucent will co-own the technology developed by BBT
under the R&D Agreement with certain restrictions on its use, including
restrictions on licensing third parties and producing products that are plug
compatible with the products of the other party and limitations on use by BBT
solely with BBT digital loop carrier products. Although specific products to be
developed by BBT for Lucent have not been identified, the parties agreed to
identify specific development projects as soon as practicable. Lucent also
agreed that the products to be developed by BBT and the configuration of such
products would be selected with a view toward maximizing the ability of BBT to
utilize the developed technology in BBT's own digital loop carrier products. The
ability of BBT to reuse technology developed for Lucent in BBT products will
depend upon a number of factors, including the products Lucent wants BBT to
design, how alike the BBT and Lucent products will be and the design schedules
for the Lucent and BBT products. There can be no assurance, however, as to the
amount, if any, of developed products that will be reusable in BBT

                                     2 of 9

<PAGE>




digital loop carrier products. If BBT is not able to reuse substantial amounts
of the technology developed for Lucent, the value to BBT of the R & D Agreement
would be substantially decreased from BBT's expectations.

BBT and Lucent also entered into a Technology Transfer Agreement and Element
Manager Agreement on February 4, 1998 pursuant to which certain Lucent
technology is licensed to BBT. Under the Technology Transfer Agreement, Lucent
has granted BBT licenses to certain existing narrowband line card technology of
Lucent with certain restrictions on its use, including restrictions on licensing
third parties and producing products that are plug compatible with the products
of the other party and limitations on use by BBT solely with BBT digital loop
carrier products. BBT believes this narrowband line card technology will enable
BBT to increase the cost efficiency of its digital loop carrier products and
will save BBT substantial development time and development cost. Under the
Element Manager Agreement, BBT and Lucent will evaluate whether BBT will obtain
a license of Lucent's element manager technology. Whether or not BBT obtains a
license, Lucent will pay BBT $2 million for use in connection with an element
manager. If BBT does not obtain an element manager license from Lucent, BBT will
seek a license from another supplier or develop one internally.

On February 4, 1998 BBT and Lucent also executed a Manufacturing Agreement, an
agreement for Lucent to act as an original equipment supplier to BBT and an
agreement for BBT to act as an original equipment supplier to Lucent. Only the
Manufacturing Agreement contains guaranteed volumes. Under the Manufacturing
Agreement Lucent is to contract for excess manufacturing to be performed by BBT.
The Agreement provides BBT with products to sell to Lucent to absorb $18 million
of the cost of BBT maintaining its factory operations for three years. If Lucent
fails to provide orders for products in sufficient volume to absorb $18 million,
Lucent will pay BBT the amount that is not absorbed by Lucent's orders. As BBT
expects sales of BBT's current product, the FLX 2500, to be uncertain due to
regulatory delay, and to be low as Lucent transitions to its AnyMedia product,
the required absorption orders or payments will enable BBT to maintain its
manufacturing capabilities while BBT develops new products. Under the OEM
agreements, Lucent will manufacture for BBT certain special line cards utilizing
Lucent technology and BBT will sell its FLX-2500 product to Lucent. Neither
product has any guaranteed volume commitments. In addition, BBT and Lucent will
from time to time evaluate whether to add additional products to either or both
OEM agreements. It is expected such decisions will depend upon a number of
factors, including price, quality and the availability of other suppliers.

     The R & D Agreement, the Technology Transfer Agreement and the
     Manufacturing Agreement described above all contain provisions that would
     enable Lucent to terminate the agreements, including licenses and volume
     commitments, on certain conditions in a bankruptcy of BBT, material breach
     by BBT or a "Change in Control" of BBT. The Change in Control provision
     terminates February 4, 2003. Change in Control is very broadly defined in
     the agreements and may cause BBT to have to choose to forego the benefits
     of its agreements with Lucent to acquire another company, sell itself to
     another company or enter into a strategic alliance with another company,
     unless Lucent approves of the transaction. Should Lucent oppose a change of
     control as it relates to the technology transfer, BBT has a period of 18
     months to redesign the product


                                     3 of 9

<PAGE>




     architecture excluding Lucent's technology. In addition, BBT could lose the
     benefits of the agreements with Lucent if a company acquires a control
     position in BBT stock through market purchases without BBT's consent. A
     Change of Control occurs upon any one of the following circumstances or
     events: (i) The stockholders of BBT approve a transaction, including,
     without limitation, a merger or consolidation (however denominated or
     effectuated), with an Acquiror, including, without limitation, a merger or
     consolidation, or series of transactions with the same Acquiror
     ("Combination"), and immediately after such transaction(s) less than 60% of
     the combined voting power of the then-outstanding securities of BBT or the
     Acquiror, will be held in the aggregate by the holders of securities
     entitled, immediately prior to such Combination, to vote generally in the
     election of directors of BBT ("Voting Securities"); (ii) The stockholders
     of BBT approve the sale or transfer of all or substantially all of its
     assets to any other person or entity, and less than 60% of the combined
     voting power of the then-outstanding Voting Securities of such Acquiror
     immediately after such transaction will be held in the aggregate by the
     holders of the Voting Securities of BBT immediately prior to such sale;
     (iii) An Acquiror acquires in one or a series of transactions beneficial
     ownership of more than 40% of the outstanding shares of Voting Securities
     of BBT; (iv) The stockholders of BBT approve a plan of complete liquidation
     or dissolution of BBT; (v) Any Acquiror obtains direct or indirect Control
     (as herein defined) over BBT and, in Lucent's reasonable judgment, such
     Control may threaten Lucent's interests. For the purposes of this
     subsection, the term "Control" means the possession directly or indirectly
     of the power to direct or cause the direction of the management or policies
     of BBT, whether through the ability to exercise voting power, by contract
     or otherwise; (vi) At any time, Continuing Directors (as herein defined)
     shall not constitute at least 50% of the members of the Board ("Continuing
     Director" means (i) each individual, who has been a director of BBT for at
     least twelve (12) consecutive months before such time and (ii) each
     individual who was nominated or elected to be a director of BBT by at least
     a majority of the Continuing Directors at the time of such nomination or
     election); or (vii) Any other transaction which has the effect of causing
     the substantive changes in BBT described in any of the preceding
     paragraphs. The term "Acquiror" shall mean one person or entity, or two or
     more persons and/or entities constituting a "group" for purposes of the
     Securities Exchange Act of 1934, as amended.

                  Business Strategy.

         The agreements with Lucent described above represent the first
component of BBT's new strategy to leverage BBT's core broadband competencies in
local loop infrastructure and improve BroadBand's financial position. The second
component of BBT's strategy is a plan to introduce new products that capitalize
on the growth in the loop access market attributable to increasing Internet and
data traffic. The third component of BBT's strategy is to form strategic
alliances to enhance the FLX-2500 to meet the emerging Full Service Access
Network ("FSAN") standard. FSAN is a global standard being developed by a
22-member interest group which includes 11 international and United States
telephone companies and 11 vendors, including BBT. The FSAN architecture is a
high bandwidth, asynchronous transfer mode mission (ATM), passive optical
network (PON), xDSL similar to the FLX-2500 architecture. BBT's management
believes that the FLX-2500 is positioned to evolve

                                     4 of 9

<PAGE>



to meet the FSAN standard. There can be no assurance BBT will be able to
successfully implement its business strategies. Failure to implement any one or
more of the parts of the business strategy is likely to have a material adverse
effect on BBT.

         Management Changes.

         Lawrence A. McLernon resigned as a director of BBT, effective as of
January 26, 1998. Salim Bhatia resigned as a director of BBT and as Chairman of
the Board of Directors for BBT effective as of January 31, 1998. John R.
Hutchins, III was elected to replace Mr. Bhatia as Chairman of the Board. Mr.
Hutchins previously served as Chairman of BBT until April 1, 1997.

         Risks.

         Although management believes the relationship with Lucent offers
certain opportunities to BBT, the relationship includes certain risks as well.

         As disclosed in prior filings, the relationship between BBT and Lucent
relating to SDBAS arising out of the November 1995 Exclusive Agreement did not
meet BBT's expectations and resulted in substantially lower than expected sales
volume. There can be no assurances the new relationship with Lucent will not
fail to meet BBT's expectations. BBT's relationship with Lucent, which was
designed to leverage the intellectual property and complimentary product
offerings, may also adversely affect the prospect for partnership with others in
the telecommunications industry, especially in light of restrictions contained
in the new Lucent agreements relating to a change of control of BBT. In such a
situation BBT would have 18 months to reachitect its digital loop carrier to
remove certain intellectual property from its design. Decisions by Lucent or
rumors of a decision by Lucent that changes Lucent's relationship with BBT may
have an adverse effect on the market price of the stock of BBT. In addition,
although the relationship with Lucent is designed to be complimentary with BBT
as to product offerings, Lucent is a vendor of digital loop carrier products and
BBT's product will compete with Lucent in some circumstances. Such competition
could adversely affect the ability of BBT and Lucent to cooperate to the extent
required under the new agreements.

         To maximize the value of the new agreements with Lucent, BBT must
develop its own digital loop carrier product. Development of a new digital loop
carrier product by BBT will be subject to significant technical and other
challenges and will require a substantial investment of money and time. There
can be no assurance that BBT will be able to develop a digital loop carrier
product or that any product it develops will be attractive to customers and
price competitive with the products of competitors, including Lucent.

         Given the current regulatory and customer environment and Lucent's
transition to AnyMedia products, sales volume for BBT's only current product,
the FLX-2500, are uncertain. Accordingly, except for revenues from the new
agreements with Lucent, BBT anticipates low sales volume until its new digital
loop carrier products are introduced into the market or regulatory change
accelerates local competition for residential services.

     (d) Second, if at the end of the twenty-one (21) day period referenced in
Section 4.13(b) (as it may be extended) such dispute or disagreement has not
been resolved to the satisfaction of both parties, either Party may request in
writing that such dispute or disagreement be the subject of non-binding
mediation. Following such request, the Parties shall endeavor in good faith
promptly to identify a single person (who shall be a person with experience and
good reputation) who shall assist the Parties

                                                                              22


in discussing such dispute or disagreement and in attempting to reach a mutually
acceptable business resolution. Such mediation process shall terminate not later
than thirty (30) days following the request therefor (or such extended or
shorter period as the Parties agree is appropriate). All applicable statutes of
limitation shall be tolled during the period of mediation.

     (e) Third, if at the end of the thirty (30) day period referenced in
Section 4.13(d) (as it may be extended or shortened) such dispute or
disagreement has not been resolved to the satisfaction of both parties, either
Party (the "complainant") may commence binding arbitration by giving the other
Party (the "respondent") notice in writing (the "initiating notice") setting
forth in reasonable detail the nature of its claim and the relief requested
stating that the complainant is invoking the procedures set forth in this
Section 4.13(e) and (f) and naming the complainant's representative on the
Arbitration Panel (as defined below). Within 21 days of receipt of an initiating
notice, the respondent shall give the complainant notice in writing (the
"response") setting forth in reasonable detail: (1) the basis of its response to
the claim; (2) the nature of any counterclaim it has against the complainant
arising from the same set of facts and circumstances that gave rise to the
original claim; (3) any other counterclaim that Party wishes


<PAGE>


                                                                              23


to bring at that time (although the Party has no obligation to bring such
counterclaims at that time); (4) the relief requested; and (5) naming the
respondent's representative on the Arbitration Panel. The two representatives
shall select a third person who is mutually acceptable to them. If the
representatives fail to make such selection within twenty-one (21) days, the
complainant and the respondent shall each replace its representative with a new
representative and the new representatives shall be subject to the preceding
sentence and this sentence. Once a third person is selected, such person
together with the representatives of the complainant and the respondent shall
form the Arbitration Panel. The date upon which the Arbitration Panel is formed
shall be the "Commencement Date".

     (f) The Arbitration Panel shall conduct proceedings to determine the merits
under applicable law of the claims set forth in the initiating notice and the
response. The proceedings shall be administered by JAMS/Endispute in accordance
with its Comprehensive Arbitration Rules and Procedures in effect as of the
Effective Date, subject to the following additional rules:

          (i) the proceedings shall take place in New York City;

          (ii) the Arbitration Panel (including, if necessary, any
     replacement(s) to the Arbitration Panel)


<PAGE>


                                                                              24


     shall be selected as set forth in Section 4.13(e);

          (iii) the available relief shall include damages, injunctive relief
     and equitable relief to the extent allowed under the applicable law, this
     Agreement and any other agreement between the parties;

          (iv) the parties shall attempt in good faith promptly to agree on the
     nature and extent of any discovery in connection with the arbitration,
     provided that, in the absence of such agreement, discovery shall be
     governed by JAMS/Endispute's Comprehensive Arbitration Rules and
     Procedures. In addition, the applicable law with respect to privilege and
     other protections from disclosure, including the work product doctrine
     shall apply;

          (v) the final decision of the Arbitration Panel (the "Award") shall be
     issued within six months of the Commencement Date (the date of issuance of
     the Award being the "Award Date") and must be joined by at least two
     members of the Arbitration Panel;

          (vi) each party to the proceedings shall pay its own costs in
     connection with the proceedings, including the costs and expenses of its
     representative on the Arbitration Panel, and the parties shall share
     equally the other costs of the proceedings, including the fees of the third
     member of the Arbitration Panel, except

                                                                              25


     that the prevailing party shall be entitled to recover its attorneys' fees
     incurred in prosecution thereof.

     (g) In accordance with the Federal Arbitration Act, 9 U.S.C. ss. 1 et seq.,
the Award shall be final and binding and judgment thereon may be entered by any
state or federal court having jurisdiction thereof.

     (h) Nothing in this Section 4.13 shall be construed to preclude either
party from seeking injunctive declaratory or other provisional relief in a court
of competent jurisdiction to prevent imminent irreparable harm. The dispute
resolution procedures set forth herein shall be stayed pending disposition of
any application for such relief. The Parties agree that a court of competent
jurisdiction may consider the merits of any claim that is subject to the dispute
resolution procedures set forth herein to the extent necessary to resolve any
permissible application for injunctive declaratory or other provisional relief.

     SECTION 4.14. Compliance with Law. Nothing in this Agreement shall obligate
a Party to act in violation of any applicable legal requirement or prohibition.
To the extent that any provision of this Agreement may be construed at any time
to impose such an obligation upon a Party, that provision shall be deemed
modified insofar as necessary (but only to the least extent necessary) to
relieve the Party of

such obligation and to allow the Party to comply in full with all applicable
legal requirements or prohibitions.

                                  ARTICLE XXVI

                               Testing and Quality

     SECTION 26.01. Supplier will perform a factory systems test in accordance
with the following criteria:

     (a) The term "system" is meant to describe a complete ASE transport system
including all standard subsystems. For normal production, it is acceptable to
test subsystems in a "system configuration" test environment consisting of a
captive test bed to which the specific subsystem under test is connected. These
arrangements are acceptable if the periodic qualification testing is used to
revalidate such test configurations. This can be accomplished by first testing a
defined system in the production manner followed by qualification testing of the
same system (using a full system environment).

     (b) Correction of any production testing program deficiencies identified
will be made immediately. System configuration testing will be conducted on
Materials to demonstrate the ability to achieve stable, fault free operation for
a reasonable period of time while running operational exercises and diagnostic
routines at 120 degrees Fahrenheit. The testing duration will be such that


<PAGE>
                                                                              33



adherence to reliability requirements can be demonstrated. Manufacturing testing
burn-in intervals will be of sufficient duration, so that when coupled with
normal installation and turnover intervals, early-life reliability performance
at cut over will be at or below two and one-half times the steady-state
reliability level. That is, the instantaneous failure rate at cut over shall be
less than or equal to two and one-half times the expected steady-state
instantaneous failure rate.

     (c) Periodically, an entire system will be subjected to qualification
testing to assure that product and manufacturing processes continue to
demonstrate conformance to design intent. All Material shipped loose and not in
a complete system configuration, such as spares and additions for growth, shall
receive testing to demonstrate functionality and quality levels at least
equivalent to Material embedded in systems. Manufacturing testing and burn-in
intervals will be of sufficient duration so that infant mortality failure rate
of Material shipped is no greater than two and one-half times the predicted
steady-state failure rate.

     (d) Testing performed will provide verification of operability as
completely as possible with current manufacturing test capabilities. This will
include verification of performance over ranges of design limits to assure
operation in all possible field applications. Testing in a simulated use
environment (test bed) will normally be included as one of the test steps.
************ ******** or Customer owned circuit packs returned for repair must
be tested in a simulated use environment as part of the repair process. Returned
circuit packs which are found to be operational upon their receipt will be
tested under heat (120(Degree) F) to identify thermostatic devices which may
have been the cause for return. Return and repair results data shall be made
available to ************** or *************** agent or to Customer or
Customer's agent. The effectiveness of simulated use environments or the manner
of subsystem testing employed must have been verified as consistent with a full
level system test. This verification must have been conducted initially and at
periodic intervals as part of the periodic qualification discussed above. When
internal machine diagnostics are used in the testing of systems, subsystems or
Material shipped loose, the effectiveness of those diagnostics in the
identification of defective Material must be verified initially and again as
part of the periodic product qualification test.

     SECTION 26.02. Unless Company gives Supplier written notice to the
contrary, Supplier shall notify Company when each installment of Material is
ready for



<PAGE>
                                                                              34


inspection and Company and its customer (i.e., ************* or one of the
Customers) or its customer's agent shall be given reasonable opportunity to
inspect the Material at any time prior to shipment under agreed upon Quality
Program Specifications listed in Appendix I to the FSN Agreement, as may be
changed from time to time with Supplier's written concurrence. Inspection or
failure to inspect on any occasion shall not affect Company's rights under
warranty or other provisions of this Supply Agreement. Supplier shall make
available at no additional cost to Company, such production testing facilities,
labor, data, specifications, procedures and such other documents, and assistance
as necessary for Company and its customer or its customer's agent to perform the
inspection. In addition, Supplier shall make available to Company and its
customer or its customer's agent, at no additional charge, data obtained through
Supplier's normal routines which show results of Supplier's inspection, tests
and audits of Material as specified in the agreed upon Quality Program
Specifications. Such data shall be sufficient to demonstrate that the Material
meets all quality and reliability requirements.

     SECTION 26.03. Commitment to quality is a primary requirement of this
Supply Agreement and as used herein shall mean conformance to the terms,
conditions and specifications of this Supply Agreement. Supplier will ensure
continued quality improvement in the Materials covered in this Supply Agreement.
Supplier will demonstrate commitment to a "Quality Improvement Process" by

                     capabilities, longer life or improved transmission margins.

              (c)    Providing changes in design which result in important cost
                     savings to Supplier or Company.

              (d)    Conditions of mandatory nature, for example, the
                     fulfillment of federal registration or future compatibility
                     requirements, or for conditions of sufficient importance to
                     be intended for universal application (change to be shown
                     as "recommended"). The final classification of any product
                     change proposed by Supplier will be by mutual agreement
                     between Supplier and Company.

                                                                              45


deemed necessary, Supplier shall, pursuant to the provision of this Agreement
governing repair of Material not covered under warranty, make arrangements for
the necessary Material replacement or modification at prices and schedules to be
mutually agreed upon by Company and the Supplier prior to implementation.
Documentation related thereto shall be provided by Supplier as specified for
Class A above.

     SECTION 35.06. Company shall provide Supplier sixty (60) calendar days to
one hundred eighty (180) calendar days prior written notice of all Engineering

requested Engineering Changes; if not feasible, Supplier will inform Company of
reason(s); if feasible, Supplier shall provide a quote of not less than thirty
(30) calendar days duration, on cost to be incurred by Company should Company
request supplier to implement change(s).

     SECTION 35.07. To assist Company in determining the amount of the equitable
adjustment, the Supplier agrees to make available to Company pricing data
required by Company to accomplish the end. If the cost of supplies or materials
made obsolete or excess as a result of such change is included in the Supplier's
claim for adjustment, Company shall have the right to prescribe the manner of
disposition of such supplies or materials. Any claim for adjustment under this
clause must be asserted within thirty (30) calendar days from the date the
change is ordered. However, if Company determines that the facts justify such
action, it may receive, consider and adjust any such claim asserted at any time
prior to the date of final payment. Nothing contained in this clause shall
excuse the Supplier from proceeding with the work so changed.

     SECTION 35.08. Change Induced Problems. If, after any engineering or any
other change by Supplier, Company determines and notifies Supplier that Material
or Parts do not operate in accordance with the specifications or fail to meet
any agreed upon acceptance test procedure, Supplier will evaluate any defective
Material or Part after their receipt and will notify Company of the result of
its evaluation and, if needed, its corrective action plan, within ten (10)
calendar days.

applicable requirements established pursuant to such agreements, legislation and
regulations, and the material furnished to Company will be able to be imported
and used lawfully (and without additional taxes associated with ODCs not
reported to Company by Supplier as set forth in this clause) under all such
agreements, legislation and requirements. Supplier also warrants that it is
currently reducing, or if Supplier is not the manufacturer of the material, is

operations for the material plus all ODCs used by Supplier's vendors and any
other vendors in producing components or other products incorporated into the
material sold to Company.

     SECTION 76.04. Supplier is responsible to obtain information on the ODC
content of all components and other products acquired to manufacture the
material and to incorporate such information into the total ODC content reported
to Company; provided, however, that Supplier should not include in the ODC
content those components or other products which are manufactured in the United
States. Supplier hereby warrants to Company that all information furnished by
Supplier on the ODC Content Certification is complete and accurate and that
Company may rely on such information for any purpose, including but not limited
to providing reports to government agencies or otherwise complying with
applicable laws. Supplier shall defend, indemnify and hold Company harmless of

costs and expenses (including additional ODC taxes as provided for in paragraph
one of this clause and reasonable

local laws or international agreements, and any and all amendments thereto by
reason of Company's use of reliance on the information furnished to Company by
Supplier on the ODC Content Certification or by reason of Supplier's breach of
this clause. Supplier shall cooperate with Company in responding to any inquiry
concerning the use of ODCs to manufacture the material or components thereof and
to execute without additional charge any documents reasonably required to
certify the absence or quantity of ODCs used to manufacture the material or
components thereof.

a default of any of its subcontractors or suppliers unless such default arises
out of causes beyond the control of both the Supplier and its subcontractor or
supplier and without the fault or negligence of either of them, and unless the
supplies or services to be furnished by such subcontractor or supplier are not
obtainable from other sources. If such contingency occurs, the party injured by
the other's inability to perform may elect to: (a) terminate this Supply
Agreement or part thereof as to Material or Services not already received; (b)
suspend this Supply Agreement for the duration of the delaying cause, buy or
sell elsewhere Material and/or Services to be bought or sold hereunder, and
deduct from any commitment the quantity bought or sold for which commitments
have been made elsewhere; or (c) resume performance hereunder once the delaying
cause ceases with an option in the injured party to extend the period, hereunder
up to the length of time the contingency endured. Unless written notice is given
within thirty (30) days after such injured party is apprised of the contingency,
(c) shall be deemed selected.

promptly to identify a single person (who shall be a person with experience and
good reputation) who shall assist the Parties in discussing such dispute or
disagreement and in attempting to reach a mutually acceptable business
resolution. Such mediation process shall terminate not later than 30 days
following the request therefor (or such extended or shorter period as the

statutes of limitation shall be tolled during the period of mediation.

     SECTION 93.05. Third, if at the end of the 30 day period referenced in
Section 93.04 (as it may be extended or shortened) such dispute or disagreement
has not been resolved to the satisfaction of both parties, either Party (the
"complainant") may commence binding arbitration by giving the other Party (the
"respondent") notice in writing (the "initiating notice") setting forth in
reasonable detail the nature of its claim and the relief requested stating that
the complainant is invoking the procedures set forth in Sections 93.05 and 93.06
and naming the complainant's representative on the Arbitration Panel (as defined
below). Within 21 days of receipt of an initiating notice, the respondent shall
give the complainant notice in writing (the "response") setting forth in
reasonable detail: (1) the basis of its response to the claim; (2) the nature of
any counterclaim it has against the complainant arising from the same set of
facts and circumstances that gave rise to the original claim; (3) any other
counterclaim that Party wishes to bring at that time (although the Party has no
obligation to bring such counterclaims at that time); (4) the relief requested;
and (5) naming the respondent's representative on the Arbitration Panel. The two
representatives shall select a third person who is mutually acceptable to them.
If the representatives fail to make such selection within 21 days, the
complainant and the respondent shall each replace its representative with a new
representative and the new representatives shall be subject to the preceding
sentence and this sentence. Once a third person is selected, such person
together with the representatives of the complainant and the respondent shall
form the Arbitration Panel. The date upon which the Arbitration Panel is formed
shall be the "Commencement Date".

     SECTION 93.06. The Arbitration Panel shall conduct proceedings to determine
the merits under applicable law of the claims set forth in the initiating notice
and the response. The proceedings shall be administered by JAMS/Endispute in
accordance with its Comprehensive Arbitration Rules and Procedures in effect as
of the Effective Date, subject to the following additional rules:

     (a) the proceedings shall take place in New York City;

     (b) the Arbitration Panel (including, if necessary, any replacement(s) to
the Arbitration Panel) shall be selected as set forth in Section 93.05;

     (c) the available relief shall include damages, injunctive relief and
equitable relief to the extent allowed under the applicable law, this Agreement
and any other agreement between the parties;

     (d) the parties shall attempt in good faith promptly to agree on the nature
and extent of any discovery in connection with the arbitration, provided that,
in the absence of such agreement, discovery shall be governed by
JAMS/Endispute's Comprehensive Arbitration Rules and Procedures. In addition,
the applicable law with respect to privilege and other protections from
disclosure, including the work product doctrine, shall appply.

     (e) the final decision of the Arbitration Panel (the "Award") shall be
issued within six months of the Commencement Date (the date of issuance of the
Award being the "Award Date") and must be joined by at least two members of the
Arbitration Panel;

     (f) each party to the proceedings shall pay its own costs in connection
with the proceedings, including the costs and expenses of its representative on
the Arbitration Panel, and the parties shall share equally the other costs of
the proceedings, including the fees of the third member of the Arbitration
Panel, except that the prevailing party shall be entitled to recover its
attorneys' fees incurred in prosecution thereof.

     SECTION 93.07. In accordance with the Federal Arbitration Act, 9 U.S.C. ss.
1 et seq., the Award shall be final and binding and judgment thereon may be
entered by any state or federal court having jurisdiction thereof.

     SECTION 93.08. Nothing in this Article shall be construed to preclude
either party from seeking injunctive relief in a court of competent jurisdiction
to prevent imminent irreparable harm. The dispute resolution procedures set
forth herein shall be stayed pending disposition of any application for such
relief. The Parties agree that a court of competent jurisdiction may consider
the merits of any claim that is subject to the dispute resolution procedures set
forth herein to the extent necessary to resolve any permissible application for
injunctive relief.

ENGINEERING CHANGE CONTROL PROCEDURES


Supplier agrees to perform and administer all "Product Changes" in accordance
with Bell Communications Research document GR 209 CORE, Issue 2, January 1996,
titled "Generic Requirements for Product Change Notices", which is incorporated
herein by reference.

Supplier may make changes to MATERIAL, modify drawings, or make changes to
manufacturing specifications, provided the changes, modifications, or
substitutions DO NOT have an impact on the performance, reliability, form, fit,
or function of the MATERIAL without prior notification to Company. Supplier
shall maintain written records of all such changes, and make these records
available for Company's review upon request.

For such changes or modifications which DO have an impact on performance,
reliability, form, fit, or function, Supplier shall identify each such change or
modification in accordance with the classifications contained in the above Bell
Communications Research document via a Product Change Notification (PCN) form.
The Company shall immediately acknowledge receipt of the PCN to the
address/contact as stated on the PCN form and shall have thirty (30) calendar
days to advise Supplier if the proposed change or modification is unacceptable.
If Company notifies Supplier as required herein, that the proposed change or
modification is unacceptable, Supplier shall not implement such change or
modification. Company may reject any MATERIAL offered by Supplier which has been
changed or modified in a manner unacceptable to Company.

If Company has not notified Supplier that the change or modification is
unacceptable within thirty (30) calendar days following issuance of the Change
Notification, Supplier shall implement the change or modification as described
in the Change Notification.

If during the review of a proposed Product Change Notification, which has a
classification of either A or AC, issued by Supplier during the Warranty period
of the affected MATERIAL, the Company determines that implementation of the
PRODUCT CHANGE will cause the Company to incur "unreasonable expenses" such as,
but not limited to, expenses resulting from escorting Supplier's personnel to
numerous Company locations containing affected MATERIFAL or repeated product
changes to the same item of MATERIAL within a one (1) year time period, the
Company shall so notify Supplier, in writing, prior to the implementation of
such PRODUCT CHANGE. Upon such notification, the Company and Supplier shall
jointly determine the implementation procedure which will utilize the Supplier's
and/or Company's personnel in the most cost effective manner.


<PAGE>



If Supplier and the Company conclude the agreed to implementation procedure will
probably cause the Company to incur "unreasonable expenses", the Company and
Supplier shall jointly determine the likely extent of such expenses and agree,
in writing, to a "not to exceed" estimate for such expenses. In no event shall
such estimate exceed the Company's purchase price for the MATERIAL to be
changed. The Company shall track and record all such expenses associated with
the PRODUCT CHANGE. Upon completion of its efforts, the Company shall submit to
Supplier, for reimbursement by Supplier, an invoice of the Company's
"unreasonable expenses" within forty-five (45) calendar days after the Company's
receipt of such invoice.

Issuing a Class A or AC product Change Notification shall not constitute an
agreement to provide such a change, but shall be construed as a recommendation
by the Supplier that the change is absolutely necessary.

Warranty Eligibility System


                        Warranty Eligibility System (WES)
                                   Transaction


The Warranty Eligibility System (WES) tracks a serialized product from
manufacturing to the customer and provides up-to-date information about the
product's warranty status. In order to accomplish this, WES receives data from
entities whose functions affect an item's warrantability.

At the end of the manufacturing, shipping, or repair processes, information
about an item will be sent to WES for inclusion on the Warranty Database. This
file can be sent to WES using

1)  UNIX file transfer at,
         /usr/spool/uucppublic/receive/wes/origsystem/WESXXNNNN 
         where origsystem is the UNIX machine originating the file XX is a
         location code entry in the location table and NNNN is the sequence
         number on the header record.

2)  or by placing the formatted file on a floppy disk and mailing the disk
    directly to the WES group at:
         Lucent Technologies
         Westwood of  Lisle
         Attn.:  L. Fitzgerald
         2443 Warrenville Rd.
         Lisle,  IL  60532


Batch files received for processing by WES must be processed by a Header Record
as attached. Following the Data Records must be a Trailer Record also attached.
The Header and Trailer Records are interrogated by WES and messages are returned
to the sending location indicating the status of each file transmitted to WES.

These files should be sent at least once a week, depending on volume, in order
to keep the database current. That data needs to be formatted as shown on the
following page.

                                        9

                                    DISPUTES
        
   
9.01 (a) The  following  procedures  shall apply to any dispute or  disagreement
between the Parties or any of their Subsidiaries arising out of this Agreement.

(b)  First:

          (i) either  Party may give  written  notification  of such  dispute or


                                       11
<PAGE>


     disagreement to the other Party and

          (ii) the Parties  shall  communicate  with each other  promptly with a
     view to  resolving  such  dispute or  disagreement  within 21 days (or such
     extended period as the Parties agree is appropriate in any case) after such
     written notification is given.

(c) The giving of any notice  regarding any dispute or  disagreement  under this
Section  9.01 shall toll the running of all  applicable  statutes of  limitation
until the later of (i) 90 days  following  the giving of such  notice or (ii) 30
days following the  termination of  discussions  between the Parties  concerning
such dispute or disagreement.

(d) Second, if at the end of the 21 day period referenced in Section  9.01(b)(as
it may be extended)  such dispute or  disagreement  has not been resolved to the
satisfaction  of both  parties,  either  Party may request in writing  that such
dispute or disagreement be the subject of non-binding mediation.  Following such
request,  the Parties shall endeavor in good faith promptly to identify a single
person (who shall be a person with  experience  and good  reputation)  who shall
assist the Parties in discussing such dispute or disagreement  and in attempting
to reach a mutually acceptable business resolution. Such mediation process shall
terminate  not  later  than 30 days  following  the  request  therefor  (or such
extended or shorter period as the Parties agree is appropriate).  All applicable
statutes of limitation shall be tolled during the period of mediation.

(e) Third, if at the end of the 30 day period  referenced in Section 9.01(d) (as
it may be extended  or  shortened)  such  dispute or  disagreement  has not been
resolved to the satisfaction of both parties,  either Party (the  "complainant")
may commence  binding  arbitration by giving the other Party (the  "respondent")
notice in writing (the "initiating  notice") setting forth in reasonable  detail
the nature of its claim and the relief requested stating that the complainant is
invoking  the  procedures  set  forth  in  this  (e)  and  (f)  and  naming  the
complainant's representative on the Arbitration Panel (as defined below). Within
21 days of  receipt  of an  initiating  notice,  the  respondent  shall give the
complainant  notice in writing  (the  "response")  setting  forth in  reasonable
detail:  (1) the  basis of its  response  to the  claim;  (2) the  nature of any
counterclaim it has against the  complainant  arising from the same set of facts
and  circumstances  that  gave  rise  to  the  original  claim;  (3)  any  other
counterclaim  that Party wishes to bring at that time (although the Party has no
obligation to bring such  counterclaims at that time); (4) the relief requested;
and (5) naming the respondent's representative on the Arbitration Panel. The two
representatives  shall select a third person who is mutually acceptable to them.
If the  representatives  fail  to  make  such  selection  within  21  days,  the
complainant and the respondent shall each replace its representative  with a new
representative  and the new  representatives  shall be subject to the  preceding
sentence  and this  sentence.  Once a third  person  is  selected,  such  person
together with the  representatives  of the complainant and the respondent  shall
form the Arbitration  Panel. The date upon which the Arbitration Panel is formed
shall be the "Commencement Date".

(f) The  Arbitration  Panel shall  conduct  proceedings  to determine the merits
under  


                                       12
<PAGE>


applicable  law of the  claims  set  forth  in the  initiating  notice  and  the
response.  The proceedings shall be administered by JAMS/Endispute in accordance
with its  Comprehensive  Arbitration  Rules and  Procedures  in effect as of the
Effective Date, subject to the following additional rules:

     (i)  the proceedings shall take place in New York City;

     (ii) the Arbitration Panel (including,  if necessary, any replacement(s) to
          the  Arbitration  Panel)  shall be  selected  as set forth in  Section
          9.01(e);

    (iii) the available  relief shall  include  damages,  injunctive  relief and
          equitable  relief to the extent allowed under the applicable law, this
          Agreement and any other agreement between the parties;

     (iv) the  parties  shall  attempt  in good faith  promptly  to agree on the
          nature and extent of any discovery in connection with the arbitration,
          provided that, in the absence of such  agreement,  discovery  shall be
          governed  by  JAMS/Endispute's  Comprehensive  Arbitration  Rules  and
          Procedures  and the applicable law with respect to privilege and other
          protections from disclosure, including the work product doctrine;

     (v)  the final  decision of the  Arbitration  Panel (the "Award")  shall be
          issued  within  six  months  of the  Commencement  Date  (the  date of
          issuance of the Award being the "Award Date") and must be joined by at
          least two members of the Arbitration Panel;

     (vi) each party to the  proceedings  shall pay its own costs in  connection
          with  the  proceedings,  including  the  costs  and  expenses  of  its
          representative  on the Arbitration  Panel, and the parties shall share
          equally the other costs of the proceedings,  including the fees of the
          third  member of the  Arbitration  Panel,  except that the  prevailing
          party shall be entitled to recover  its  attorneys'  fees  incurred in
          prosecution thereof.

(g) In accordance with the Federal  Arbitration Act, 9 U.S.C.  ss.1 et seq., the
Award  shall be final and  binding  and  judgment  thereon may be entered by any
state or federal court having jurisdiction thereof.

(h) Nothing in this Section  9.01 shall be  construed  to preclude  either party
from seeking  injunctive relief in a court of competent  jurisdiction to prevent
imminent  irreparable harm. The dispute  resolution  procedures set forth herein
shall be stayed pending  disposition  of any  application  for such relief.  The
Parties agree that a court of competent  jurisdiction may consider the merits of
any claim that is subject to the dispute resolution  procedures set forth herein
to the extent  necessary to resolve any  permissible  application for injunctive
relief.

understood  and agreed by the Parties that this does not prohibit  Licensee from
subcontracting  certain  activities in accordance with the provisions of Section

                             MANUFACTURING AGREEMENT

This  Agreement  is  entered  into and made  effective  as of  February  4, 1998
("Effective  Date"),  by and between  Lucent  Technologies  Inc., a  corporation
organized under the laws of the State of Delaware and having its principal place
of business at 600 Mountain  Avenue,  Murray Hill, New Jersey 07974  ("Lucent"),
and BroadBand Technologies,  Inc., a corporation organized under the laws of the
State of Delaware and having its  principal  office at 4024 Stirrup Creek Drive,
Durham, North Carolina 27709-3737 ("BroadBand") (collectively "the Parties").

                                   WITNESSETH:

WHEREAS,  Lucent is in the  business  of,  among  other  things,  producing  and
marketing telecommunications equipment and related supplies and services; and

WHEREAS,  BroadBand  manufactures  and  sells  products  related  to some of the
business of Lucent,  and Lucent  desires  BroadBand  to  manufacture  for Lucent
various Lucent products,  pursuant to Lucent specifications,  for Lucent to sell
to Lucent's customers, subject to the terms and conditions set forth herein.

NOW,  THEREFORE,  in  consideration  of the mutual promises herein set forth and
other good and valuable  consideration,  the receipt and sufficiency of which is
hereby acknowledged by the parties, BroadBand and Lucent agree as follows:

1.0 EFFECTIVE PERIOD OF AGREEMENT - The term of this Agreement shall commence on
the Effective Date, and shall,  except as otherwise  provided in this Agreement,
continue  in effect  thereafter  for a period of three years from the end of the
Preparation Period as defined herein.

1.1 PREPARATION  PERIOD - Promptly after the execution of this  Agreement,  each
Party will appoint a team of  representatives to work together on establishing a
set of procedures to be followed by the Parties in implementing  this Agreement.
That team will also  agree on the  initial  Product  Letter for  Material  to be
manufactured pursuant to this Agreement. The initial Product Letter will include
the following information:  (a) the identification of the initial Material to be
manufactured  by  BroadBand  for Lucent;  (b) the  Specifications  to be used by
BroadBand in  manufacturing  that  Material;  (c) the initial  twelve (12) month
forecast for that Material; (d) the per unit price to be charged by BroadBand to
Lucent for the Material  identified in the forecast,  and the price schedule for
repairs of the Material;  (e) the monetary  amount of  Manufacturing  Absorption
associated   with  each  unit  of  Material  in  the  initial   forecast   ("the
Manufacturing  Absorption  Rate");  (f) the warranty  period for the Material if
other than five (5) years; (g) identification of test documentation,  equipment,
or other  information  or materials to be provided by Lucent in connection  with
the  Material;  (h) the packaging  standards for each item of Material;  (i) the
freight  classification  for each item of Material;  (j) the norm for  rejection
rates and period of time to achieve  quality  levels (See  Section  50); (k) the
schedule  under which Lucent may change its forecast or purchase  order quantity
without charge;  (l) any long lead time  components,  custom  materials or other
components authorized for procurement by BroadBand;


                                                                          Page 4


<PAGE>

(m) the  percentages  for  failures  and defects of Material  referenced  in the
clause entitled PRODUCT CONFORMANCE  REVIEWS;  and (n) the identification of the
applicable Lucent quality inspection organization. These tasks will be completed
within  ninety  (90)  days  from  the  Effective  Date of this  Agreement  ("the
Preparation  Period").  The document  produced by this team will  constitute the
first  Product  Letter under this  Agreement.  Subsequent  Product  Letters will
contain the same  information as set forth in this Article.  Product Letters are
effective only when signed by both Parties.

2.0 MATERIAL - "Material" or "material" as used in this Agreement shall mean the
products  described in a Product Letter.  Such Material shall be manufactured by
BroadBand pursuant to Lucent  specifications set forth in the Product Letter and
will be sold  only to  Lucent  in  accordance  with the  terms,  conditions  and
specifications  stated in this Agreement.  Material shall be furnished to Lucent
on an as ordered basis.  "Specification(s)" as used in this Agreement shall mean
all of the specifications made part of a Product Letter.

3.0 PRICE - Prices for Material to be manufactured  hereunder shall be set forth
in the applicable Product Letter.

4.0 PAYMENT TERMS - Payment for Material  shall be due net 30 days from the date
of delivery of the  Material to Lucent or receipt of the  applicable  invoice by
Lucent, whichever occurs later.

5.0 SHIPMENT. - The Material shall be shipped FOB BroadBand's  factory.  Freight
will be prepaid  and billed as a separate  item  unless  directed  otherwise  by
Lucent.

6.0  FORECAST  OF  MATERIAL - Lucent will  provide  BroadBand  each month with a
twelve (12) month  rolling  forecast of the  Material it plans to order and have
delivered during each month. The first such forecast will be prepared during the
Preparation  Period.  Lucent will provide more frequent  updates as appropriate.
Consistent  with the change order  provisions  set forth in the clause  entitled
"PURCHASE  ORDERS",  these  forecasts  shall  constitute a commitment by Lucent.
BroadBand agrees to acknowledge  receipt of and provide  acceptance of forecasts
in  writing  within  ten (10)  working  days  from  receipt.  Lucent  will  make
reasonable  efforts  to  provide  balanced  forecasts  and  purchase  orders for
Material to avoid sharp increases or decreases in production.

7.0 PURCHASE  COMMITMENT - Following the end of the Preparation  Period,  Lucent
shall  purchase  a volume  of  Material  from  BroadBand  sufficient  to  enable
BroadBand to absorb the amounts of the  manufacturing  costs  identified  in the
definition  of  Manufacturing  Absorption  set  forth  in  Article  7.1 of  this
Agreement  ("Manufacturing  Absorption")  shown below, for each indicated period
("Absorption Period"):

         ********          End of Preparation Period through December 31, 1998

         ********          January 1, 1999 through June 30, 1999

         ********          July 1, 1999 through December 31, 1999

         ********          January 1, 2000 through June 30, 2000


                                                                          Page 5


<PAGE>



         ********          July 1, 2000 through December 31, 2000

         ********          January 1, 2001 through May 1, 2001.
         -----------

         $18 million       Total

Purchases will be arranged, to the extent practicable, to provide the same level
of Manufacturing  Absorption each quarter. If at the end of the first Absorption
Period,  Lucent has not purchased sufficient Material to absorb ************* of
Manufacturing  Absorption,  Lucent  shall pay the  deficiency  in  Manufacturing
Absorption to BroadBand  within  thirty (30) days of the end of such  Absorption
Period.  A  similar  calculation  will be  made  at the  end of each  subsequent
Absorption  Period.  If this  Agreement is  terminated  by Lucent other than for
cause or the end of the last  Absorption  Period is  reached  without  BroadBand
having  received   eighteen  million  dollars   ($18,000,000)  in  Manufacturing
Absorption, Lucent shall pay the deficiency to BroadBand within thirty (30) days
of such termination or end of Absorption  Period.  The Manufacturing  Absorption
Rate associated  with the initial  Material to be manufactured by BroadBand will
be established  by the  representatives  of the Parties  during the  Preparation
Period.  Consistent  with the  process  established  by the  Parties  during the
Preparation Period, the Parties' representatives will meet monthly following the
Preparation Period to establish the Manufacturing  Absorption Rate for each unit
of Material identified in Lucent's then current forecast.

7.1 The term "Manufacturing Absorption", as used in Article 7.0 and elsewhere in
this Agreement,  shall mean all costs  associated with direct and indirect labor
and related overheads, depreciation of capital equipment, facility amortization,
manufacturing variance and other direct and indirect expenses. The term does not
include direct material acquisition costs.

     7.1.1 Direct labor and associated  overhead:  includes  salaries and fringe
     benefits of personnel who are manufacturing/testing products;

     7.1.2 Indirect labor and associated overhead:  includes salaries and fringe
     benefits of personnel in support of production,  quality,  test and process
     engineering, documentation, etc.

     7.1.3 Direct  expenses:  expenses  associated  with the  manufacture of the
     product (e.g., line scrap, engineering change orders,  obsolesence,  unique
     tools, etc.)

     7.1.4 Indirect expenses:  associated expense not directly attributable to a
     specific  product,  but  nonetheless  layered  over  the  operation  (e.g.,
     facilities, heat, transportation, etc.)

     7.1.5 Manufacturing variance: does not include product warranty cost.


                                                                          Page 6

8.0 SHIPPING - BroadBand shall: (1) ship the Material covered by a forecast or a
purchase order substantially  complete unless instructed otherwise;  (2) ship to
the destination  designated in the purchase order; (3) ship according to routing
instructions  given by Lucent; (4) place the Agreement and purchase order number
on all  subordinate  documents;  (5)  enclose  a  packing  memorandum  with each
shipment  and,  when more than one  package is  shipped,  identify  the  package
containing  the  memorandum;  (6) mark the purchase order number on all packages
and shipping  papers;  and (7) not ship Material more than five (5) working days
earlier  or five (5)  working  days later than the  agreed  upon  shipment  date
without Lucent's prior written authorization.  Adequate protective packing shall
be furnished at no additional charge.  Shipping and routing instructions must be
furnished  or  altered  by  Lucent  in  writing.  If  BroadBand  does not make a
reasonable  effort  to  comply  with  the  terms of the  purchase  order or with
Lucent's written shipping or routing  instructions,  BroadBand authorizes Lucent
to charge back to BroadBand any increased cost incurred by Lucent as a result of
BroadBand's  failure to  comply.  Lucent  agrees to review  each  shipment  upon
receipt  for  contents  and damage  and advise  BroadBand  within  fifteen  (15)
calendar  days  of  any  deficiencies.   Unless  Lucent  notifies  BroadBand  of
deficiencies  within such fifteen (15) day period,  the shipment shall be deemed
accepted.

9.0 SHIPPING  INTERVAL - The delivery  schedule and interval  applicable to each
purchase  order will be agreed upon by BroadBand and Lucent and set forth in the
purchase order.

9.1 If BroadBand  exceeds the delivery  intervals then, in addition to all other
rights and remedies at law or equity or otherwise,  and without any liability or
obligation  of Lucent,  Lucent shall have the right to: (a) cancel such purchase
order with regard to the affected  Material  following the  expiration of a five
(5) business day grace period or (b) extend such  delivery date to a later date,
subject,  however, to the right to cancel as in (a) preceding if delivery is not
made or performance  is not completed on or before such extended  delivery date.
If Lucent  elects to extend  such  delivery  date,  BroadBand  shall  absorb the
difference between the charges to ship via normal transportation and the charges
to ship  premium  overnight.  The grace period will be extended by the amount of
any delay caused by delay in BroadBand receiving parts,  information or services
from Lucent or any of its affiliates that Lucent has agreed to provide under the
relevant Product Letter or other writing executed by Lucent.

9.2 If a purchase  order is  canceled by Lucent  pursuant  to the above,  Lucent
shall have the right to retain or return any or all Material received by or paid
for by Lucent under such purchase order. Within fifteen (15) days of BroadBand's
receipt of returned Material,  BroadBand shall reimburse Lucent for the costs of
shipping the  Material  returned to  BroadBand  and for any  amounts,  including
shipping costs, previously paid by Lucent for the Material. Lucent shall pay for
any  Material  it retains at the  prices  set forth in the  purchase  order or a
Product  Letter.  Lucent shall receive credit for the  Manufacturing  Absorption
Rate associated with canceled orders.

9.3 If, during the course of this Agreement, BroadBand determines that BroadBand
will no longer be able to ship  within  the  agreed  interval,  BroadBand  shall
immediately  notify  Lucent's buyer to that effect.  BroadBand shall also notify
Lucent's buyer, as soon as it becomes  apparent,  if BroadBand is unable to meet
the delivery date for an order.


                                                                          Page 7

10.0 FREIGHT  CLASSIFICATION - Material  purchased under this Agreement shall be
shipped to Lucent or Lucent's  customers subject to freight charges  appropriate
for  goods  classified  as set forth in a Product  Letter or a  purchase  order.
BroadBand  shall  indicate on the bill of lading that  Lucent's  contract  rates
apply.

11.0 SPECIFICATIONS OR DRAWINGS - The Product Letters will include manufacturing
specifications   (referred   to  herein   as   "Technical   Specifications"   or
"Specifications")  for Lucent  products to be  manufactured  by  BroadBand.  The
Specifications  for the Material included on the initial forecast will be agreed
to during the Preparation Period. Specifications for Material to be added to any
subsequent  forecast will be agreed upon prior to inclusion of the Material on a
forecast.

     In accordance  with the  notification  requirements  outlined in the clause
NOTICES,  Lucent shall  provide  BroadBand  with at least thirty (30) days prior
written notice of any change proposed to be made by Lucent in the Specifications
for Material to be manufactured by BroadBand under this Agreement.

     If the  parties do not agree to the  change  proposed  by  Lucent,  and the
parties are unable to agree on a mutually  acceptable  modification,  Lucent may
opt  to  continue  the   purchase  of  the   Material   under  the  agreed  upon
Specifications  or cancel  any  existing  orders  for that  Material;  provided,
however,  that orders for delivery within the period set forth in the applicable
Product  Letter during which Lucent may not change its purchase  order  quantity
may not be canceled  without the written  agreement of BroadBand.  BroadBand may
not unilaterally  cease  manufacture of Material subject to an accepted purchase
order.

12.0 PURCHASE ORDERS - Purchase orders issued under this Agreement shall be sent
to the following address:

               BroadBand Technologies, Inc.

               P.O. Box 13737

               4024 Stirrup Creek Drive

               Durham, North Carolina 27709-3737

                   Attention: Customer Logistics Organization

     Each purchase order shall specify:  (a) description of material,  inclusive
of any  numerical/alphabetical  identification,  (b) delivery schedule or dates,
(c)  applicable  price,  (d) location to which the material is to be shipped and
(e) location to which  invoices shall be sent for payment.  Preprinted  terms on
Lucent's purchase order form will be ignored.


                                                                          Page 8


<PAGE>


     Lucent may at any time subsequent to the issuance of a forecast or purchase
order under this Agreement  change the forecast or purchase order quantity at no
charge in  accordance  with the  schedule  set forth in the  applicable  Product
Letter.

     At the  option of  Lucent,  and at any time  during  the  Agreement  should
Material  covered by a commitment  to BroadBand  become  outdated or replaced by
later  technology or newer  components,  such commitment shall be transferred to
the new technology i.e., Material;  provided,  however, that such transfer shall
not affect Material  scheduled for delivery within the period prior to scheduled
delivery  established in the  applicable  Product Letter within which Lucent may
not amend a purchase order, without the written approval of BroadBand.

     For Lucent authorized  changes,  Lucent's liability if any, for commitments
covering  the older  technology/components(s)  shall be limited  to  BroadBand's
standard  cost  (purchase  price plus  associated  overhead in  accordance  with
BroadBand's  standard  accounting  practices) of all components for the material
ordered by BroadBand and not  transferable  to the new technology or (not usable
in BroadBand's  other  operations or saleable to BroadBand's  other  customers),
less any salvage  value  thereof.  However,  no such charges shall be payable if
within sixty (60) calendar days after notice of change,  Material  equivalent in
kind to that being terminated is ordered by Lucent from BroadBand, and Broadband
has not expended  best efforts to reduce  Lucent's  liability  for such material
during said sixty (60) calendar days period.  If requested,  BroadBand agrees to
substantiate  effort  and such  costs by,  for  example,  submitting  supporting
invoices for all material invoiced to Lucent.

     BroadBand is  authorized  by Lucent to procure long  lead-time  components,
custom  materials  and/or  components that are required to be purchased in large
minimum order quantities  (MO's) as indicated in Product Letters.  Any amendment
agreed by the parties  shall not apply to orders made by BroadBand  prior to the
effective date of the amendment,  except that an amendment  shall apply to prior
orders to the extent that BroadBand fails to take reasonable action to cancel or
reduce  an  order  made  prior  to the  date of the  amendment.  When  possible,
BroadBand  shall  purchase such items in  quantities  to meet Lucent's  expected
schedule  unless  otherwise  agreed.  If Lucent  specifies a lead  ordering time
longer than sixty (60) working days and/or BroadBand must place a longer-than-90
day firm and irrevocable order for such parts with the approved supplier, Lucent
will be  obligated to purchase  from  BroadBand  at  BroadBand's  cost the parts
required to fill  Lucent's  purchase  order upon the earlier to occur of (i) the
time the purchase  order is canceled by Lucent,  or (ii) the time this Agreement
terminates,  unless  Lucent  indicates  is will  honor a  purchase  order with a
scheduled delivery after the date this Agreement  terminates,  or (iii) the time
that such parts are no longer  required due to changes  mutually  agreed by both
parties.

     BroadBand  shall  make  available  to  Lucent,  upon  request,   reasonable
quantities of any components used in Material for Lucent's repair activity. Such
components are referred to as "Bench Stock." Reasonable  infrequent requests for
quantities of Bench Stock will be sold to Lucent at BroadBand's  actual purchase
price.

13.0  ASSIGNMENT  - BBT  shall  not  assign  any right or  interest  under  this
Agreement  (excepting  solely for moneys due or to become due) without the prior
written consent of Lucent.


                                                                          Page 9


<PAGE>


Subject  to  Lucent's  right to  terminate  upon the  occurrence  of a Change in
Control, a merger or consolidation shall not be deemed to be an assignment.  BBT
will provide Lucent with written notice of a merger or consolidation  within ten
(10)  business  days after having  knowledge or  reasonable  expectation  of the
merger or consolidation.

14.0 INTELLECTUAL  PROPERTY RIGHTS - This is not a product development contract.
In the event that Lucent desires  BroadBand to perform any product  development,
such  work  is  to  be  performed  under  a  separate  agreement.   The  Parties
acknowledge,  however,  that  from time to time,  BroadBand  may  propose  minor
changes to the manufacturing  Specifications or other elements of the Materials.
BroadBand  agrees that Lucent shall own any such changes  approved by Lucent and
incorporated  into the Material  supplied by BroadBand,  including  intellectual
property rights thereto or embodied  therein,  absent express written  agreement
otherwise.

15.0  DISTRIBUTION  RIGHTS  -  BroadBand  agrees  that it will  not  manufacture
Materials other than for Lucent.  BroadBand further agrees that it will not sell
or  offer  for  sale  anywhere  in the  world  products  which  are the  same or
essentially  the  same in  external  appearance  and/or  placement  of  external
controls as Material except for products of its own design and manufacture which
evolve from a project  under the Research  and  Development  Services  Agreement
between the parties of even date herewith. Nothing in this clause shall restrict
BroadBand  from  selling or  offering  for sale any  assembly,  subassembly,  or
component of the product which  BroadBand has  manufactured  pursuant to its own
design  specifications  or at its own  expense.  Nothing in this clause shall be
deemed to be in contradiction  with the rights of Lucent as stated in the clause
NONEXCLUSIVE MARKET RIGHTS.

16.0   CONFIDENTIALITY  -  All  Information   ("Information"  means  proprietary
specifications,  designs, plans, drawings,  software,  data, prototypes or other
business and /or  technical  information)  provided by either Party to the other
pursuant to this Agreement  shall be held in confidence by the receiving  Party;
shall be used only for the purpose of performing acts and  obligations  pursuant
to this  Agreement;  shall be reproduced  only to the extent  necessary for that
purpose;  and shall not be disclosed by the  receiving  Party  without the prior
written  approval of the disclosing  Party.  The receiving  Party may,  however,
disclose the Information to its employees,  consultants  and contractors  with a
need to  know;  provided,  that  the  receiving  Party  binds  those  employees,
consultants  and  contractors  to terms at least as  restrictive as those stated
herein,   advises  those   employees,   consultants  and  contractors  of  their
confidentiality obligations, and indemnifies the disclosing Party for any breach
of those  obligations.  Information shall be subject to the restrictions in this
section if it is in writing or other  tangible  form,  only if clearly marked as
proprietary  when disclosed to the receiving Party; or, if not in tangible form,
is  of a  nature  that  a  reasonable  person  would  conclude  is  confidential
Information,  and the  Information  is  reduced  to  writing  clearly  marked as
proprietary,  with a copy of the writing being  furnished to the receiving Party
within thirty (30) days of the  disclosure of the  intangible  information,  and
with the  writing  containing  a  notice  that the  information  was  previously
provided in  intangible  form.  These  restrictions  on the use or disclosure of
Information  shall not  apply to any  Information:  (i)  which is  independently
developed by or for the receiving Party; (ii) which is lawfully received free of
restriction from another source;  (iii) after it has become generally  available
to the public  without  breach of this  Agreement by the receiving  party;  (iv)
which at the time of disclosure  to the receiving  Party was known to that Party
free of restriction as evidenced


                                                                         Page 10


<PAGE>


by  documentation  in that Party's  possession;  (v) which the disclosing  Party
agrees in writing  is free of such  restrictions;  or (vi)  which the  receiving
Party is required to disclose  under  applicable  laws,  rules and  regulations,
provided that the  receiving  Party shall first notify the  disclosing  Party of
such required disclosure and afford the disclosing party the opportunity to seek
a protective order relating to such disclosure. All Information shall remain the
property of the disclosing  Party and shall be returned upon written  request or
upon the receiving Party's  determination  that it no longer has a need for such
Information.  The receiving  Party may retain one copy of all written  materials
returned to provide an archive record of the disclosure.

17.0 EPIDEMIC CONDITION - If, during the term of this Agreement and for one year
after the last shipment date of Material under this  Agreement,  Lucent notifies
BroadBand that any Material shows evidence of an "Epidemic  Condition" caused by
BroadBand's manufacturing and not by any specifications,  designs, instructions,
component  suppliers or materials  provided by or approved by Lucent,  BroadBand
shall prepare and propose a Corrective  Action Plan ("CAP") with respect to such
Material,  addressing implementation and procedure milestones for remedying such
Epidemic  Condition(s).  BroadBand shall provide the CAP within ten (10) days of
receiving  information from Lucent reasonably required to identify and replicate
the problem and prepare the CAP. An extension of this  time-frame is permissible
upon mutual written agreement of the parties.

     Upon notification of the Epidemic Condition to BroadBand, Lucent shall have
the  right  to  postpone  all or part of the  shipments  of  unshipped  Material
exhibiting the Epidemic Condition, by giving written notice of such postponement
to BroadBand,  pending correction of the Epidemic  Condition.  Such postponement
shall temporarily  relieve BroadBand of its shipment liability and Lucent of its
shipment acceptance liability. Should BroadBand not agree to the existence of an
Epidemic  Condition  or should  Lucent not agree to the CAP,  the matter will be
handled in accordance with the clause DISPUTE RESOLUTION.

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

(1)  Failure reports or statistical samplings show that four (4) percent or more
     of  Material  installed  or four (4)  percent or more of  Material  shipped
     during  any two  consecutive  months,  or four (4)  percent  or more of the
     Material tracked by Lucent's Field Quality  Engineering contain a potential
     safety hazard (such as personal  injury or death,  fire,  explosion,  toxic
     emissions,  etc.),  or  exhibit  a highly  objectionable  symptom  (such as
     emissions  of  smoke,  loud  noises,   deformation  of  housing)  or  other
     disconcerting symptoms of this type.

(2)  Reliability  plots of relevant  data  indicate that the material has actual
     Mean Time Between  Failures  (MTBF) of less than 80% of the MTBF stipulated
     in the Technical  Specification.  The MTBF parameter of Material is defined
     as the total operating or power-on time of any population under observation
     ("T"),  in hours,  divided by the total number of critical  failures  ("n")
     that have  occurred  during the  observed  period.  A  critical  failure is
     defined as a failure  to  operate  per the  requirements  of the  Technical
     Specification. The total operating time of a population is the summation of
     operating time of individual units in


                                                                         Page 11


<PAGE>



     that  population.  MTBF is expressed  as MTBF = T/n. An Epidemic  Condition
     shall exist when data derived from  populations  being tracked confirms the
     condition with 80% confidence.

(3)  Material  Dead on Arrival  (DOA)  failures  exceed the Epidemic DOA failure
     rate  which  is  defined  as 1.2 x DOA  specified  in the  article  of this
     Agreement entitled PRODUCT CONFORMANCE REVIEW.

     Only  major   functional  and   visual/mechanical/appearance   defects  are
considered for determining  Epidemic  Condition.  Material can be either sampled
or, at Lucent's option, 100% audited at Lucent warehouses, factories or Lucent's
customers'  locations.  If material is sampled, the data must have 80% or better
statistical confidence.

     For the purpose of this  Agreement,  functional DOA shall be defined as any
material  that  during  the  test,  installation  or upon its first use fails to
operate as expected or specified. Visual/mechanical/appearance DOA is defined as
any material  containing  one or more major defects that would make the material
unfit for use or installation.

     An  Epidemic   Condition  shall  not  include   failures  due  to  customer
misapplication,  utilization  of  parts  not  approved  by  BroadBand,  or chain
failures induced by internally or externally integrated subassemblies.

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

(a)  Incorporate  the remedy in the  affected  Material in  accordance  with the
     Engineering  Change  Control  procedures  set forth in Attachment A to this
     Agreement.

(b)  Ship  all  subsequent  material  incorporating  the  required  modification
     correcting the defect(s) at no additional charge to Lucent; and

(c)  Repair and/or replace material that caused the Epidemic  Condition.  In the
     event that  Lucent  incurs  costs due to such  repair  and/or  replacement,
     including  but not limited to labor and  shipping  costs,  BroadBand  shall
     reimburse Lucent for such reasonable costs. BroadBand shall bear risk of in
     transit loss and damage for such repaired and/or replaced material.

     BroadBand  and Lucent  shall  mutually  agree in writing as to the remedy's
implementation  schedule.  BroadBand shall use its best efforts to implement the
remedy in accordance with the agreed-upon schedule.

     If BroadBand is unable to develop a mutually  agreeable remedy, or does not
adequately  take into account the business  interests of Lucent,  as  reasonably
agreed by the parties,  Lucent may (1) develop and implement such remedy and, in
such  case,  reasonable  implementation  costs and risk of  in-transit  loss and
damage  shall be  allocated  between  the  parties as set forth in this  clause,
and/or (2) cancel  postponed  orders  without  liability and return all material
affected by such Epidemic Condition for full refund, payable by BroadBand within
thirty (30) days after


                                                                         Page 12


<PAGE>


receipt of returned  material  (with risk of loss or in-transit  damage borne by
BroadBand) and/or (3) terminate this Agreement without further liability.

18.0 FORCE  MAJEURE - Neither party shall be held  responsible  for any delay or
failure in performance of any part of this Agreement to the extent such delay or
failure  is caused by fire,  flood,  strike,  civil,  governmental  or  military
authority,  act of God, or other  similar  causes beyond its control and without
the  fault  or  negligence  of  the  delayed  or  non-performing  party  or  its
subcontractors. BroadBand's liability for loss or damage to Lucent's material in
BroadBand's  possession or control shall not be modified by this clause.  When a
party's delay or  nonperformance  continues for a period of at least thirty (30)
days,  the other party may  terminate,  at no charge,  any order affected by the
force  majeure  condition.  In  addition,  the other  party may  terminate  this
Agreement in the event that a force majeure  condition  persists for a period of
at least six (6) months within which 50% or more of the Material  forecast to be
delivered  and paid for during such period is  affected.  Lucent  shall  receive
credit for the Manufacturing  Absorption  associated with the Material for which
orders are canceled by Lucent under this Article.

19.0 HEAVY METALS AND/OR CFC IN PACKAGING - BroadBand warrants to Lucent that no
lead,  cadmium,  mercury or hexavalent chromium have been intentionally added to
any packaging or packaging  component (as defined under  applicable  laws) to be
provided to Lucent under this  Agreement and that  packaging  materials were not
manufactured  using and do not contain  chlorofluorocarbons.  BroadBand  further
warrants to Lucent that the sum of the  concentration  levels of lead,  cadmium,
mercury and hexavalent  chromium in the package or packaging  component provided
to Lucent  under this  Agreement  does not exceed  100 parts per  million.  Upon
request, BroadBand shall provide to Lucent Certificates of Compliance certifying
that the packaging and/or packaging components provided under this Agreement are
in compliance with the requirements set forth above in this clause.

20.0  IDENTIFICATION  - BroadBand  shall not,  without  Lucent's  prior  written
consent,  engage in publicity  related to this Agreement,  or make public use of
any   Identification   in  any   circumstances   related   to  this   Agreement.
"Identification" means any semblance of any trade name, trademark, service mark,
insignia,   symbol,  logo,  or  any  other  designation  or  drawing  of  Lucent
Technologies  or its  affiliates.  BroadBand  shall  remove  or  obliterate  any
Identification  prior to any use or disposition of any material  rejected or not
purchased by Lucent.  Lucent  recognizes  that BroadBand is a public company and
that  some  disclosure  of  this  Agreement  by  BroadBand  may be  required  by
applicable law.

21.0  IMPLEADER  - Neither  party shall  implead or bring an action  against the
other  based on any  claim by any  person  for  personal  injury  or death to an
employee of the other party for which the other party has previously  paid or is
obligated to pay worker's compensation benefits to such employee or claimant and
for which such  employee  or claimant  could not  otherwise  bring legal  action
against the other party.

22.0 INDEMNITY - At Lucent's request, BroadBand agrees to indemnify,  defend and
hold harmless  Lucent,  its  affiliates,  customers,  employees,  successors and
assigns  (all  referred to as  "Lucent")  from and against any losses,  damages,
claims,  fines,  penalties and expenses (including  reasonable  attorney's fees)
that arise out of or result from: (1) injuries or death to persons or


                                                                         Page 13


<PAGE>


damage to  property,  including  theft,  in any way  arising out of or caused or
alleged to have been  caused by the work or services  performed  by, or material
provided by BroadBand or persons furnished by BroadBand; or (2) assertions under
Workers' Compensation or similar acts made by persons furnished by BroadBand.

     BroadBand agrees to indemnify, defend (with counsel selected by Lucent) and
hold Lucent and Lucent's affiliates and the directors,  officers,  shareholders,
employees,  tenants,  contractors,  assigns and successors and their  affiliates
harmless from any claims (including  without  limitation  third-party claims for
personal injury or real or personal  property damage),  actions,  administrative
proceedings  (including  informal  proceedings),  judgments,  damages,  punitive
damages,  penalties,  fines,  liabilities  (including sums paid in settlement of
claims),  interest or costs,  including  attorneys' fees (including any fees and
expenses incurred in enforcing this indemnity), consultant fees, and expert fees
sought  from or  asserted  against  Lucent  in  connection  with  the  presence,
suspected  presence,  release,  suspected  release,  or threat of release of any
Hazardous Substance, whether into the air, soil, surface water or groundwater at
any and all of the  manufacturing  facilities  owned,  operated and/or leased by
BroadBand.

23.0  INFRINGEMENT - BroadBand  shall  indemnify and save harmless  Lucent,  its
affiliates and their customers, officers, directors, and employees (all referred
to  in  this  clause  as  "Lucent")  from  and  against  any  losses,   damages,
liabilities,  fines,  penalties,  and expenses (including  reasonable attorneys'
fees) that arise out of or result from any and all claims (1) of infringement of
any patent,  copyright,  trademark or trade secret right, or other  intellectual
property right,  private right, or any other  proprietary or personal  interest,
and  (2)  related  to  the   manufacturing   processes   used  by  BroadBand  in
manufacturing  Material under this Agreement (an "Infringement  Claim").  If the
Infringement Claim arises solely from BroadBand's  adherence to Lucent's written
instructions  regarding  services or tangible or  intangible  goods  provided by
BroadBand  ("Items") and if the Items are not (1) commercial  items available on
the  open  market  or the  same as  such  items,  or (2)  items  of  BroadBand's
designated origin, design or selection, Lucent shall indemnify BroadBand. Lucent
or BroadBand (at Lucent's  request)  shall defend or settle,  at its own expense
any demand,  action or suit on any Infringement Claim for which it is indemnitor
under the  preceding  provisions  and each shall timely  notify the other of any
assertion against it of any Infringement Claim and shall cooperate in good faith
with the other to facilitate the defense of any such Claim.

 24.0 INSIGNIA - Upon Lucent's written request,  "Insignia",  including  certain
trademarks,  trade names,  insignia,  symbols,  decorative  designs or packaging
designs of Lucent, or evidences of Lucent's  inspection will be properly affixed
by BroadBand to the material furnished or its packaging.  Such Insignia will not
be  affixed,  used  or  otherwise  displayed  on the  material  furnished  or in
connection  therewith  without written  approval by Lucent.  The manner in which
such  Insignia  will be  affixed  must be  approved  in  writing  by  Lucent  in
accordance with standards  established by Lucent. Lucent shall retain all right,
title and  interest  in any and all  packaging  designs,  finished  artwork  and
separations  furnished  to  BroadBand.  This  clause  does not  reduce or modify
BroadBand's obligations under the IDENTIFICATION and USE OF INFORMATION clauses.


                                                                         Page 14

32.0  ENVIRONMENTAL  WARRANTY  LIMITATION - The  warranties  and  indemnities of
BroadBand  in  the  clauses  INDEMNITY,  OZONE  DEPLETING  CHEMICALS  and  TOXIC
SUBSTANCES AND PRODUCT  HAZARDS shall not apply to materials  provided by Lucent
or manufactured by another supplier to a Lucent specification.

33.0 ORDERING COMPANIES - Lucent or any affiliated corporation,  partnership, or
venture,  both U.S. and foreign,  as may be designated in writing by Lucent, may
order under this Agreement. For the purpose of this Agreement, the term "Lucent"
shall  mean the  corporation  or other  entity  which  enters  into or  issues a
contract or order under this Agreement. An affiliated corporation,  partnership,
or venture is an entity, a majority of whose voting stock or ownership  interest
is owned  directly or indirectly  by Lucent.  Any contract or order issued under
this Agreement will be a contractual  relationship  between Lucent and BroadBand
and BroadBand shall look only to Lucent for performance of Lucent's  obligations
under such contract or order.

34.0 OZONE DEPLETING  CHEMICALS - Subject to the clause  ENVIRONMENTAL  WARRANTY
LIMITATION,  BroadBand  hereby  warrants  that  it  is  aware  of  international
agreements  and pending  legislation  in several  nations,  including the United
States, which would limit, ban and/or tax importation of any product containing,
or   produced   using   ozone   depleting    chemicals    ("ODCs"),    including
chloroflurocarbons,  halons and certain chlorinated  solvents.  BroadBand hereby
warrants  that the material  furnished to Lucent will conform to all  applicable
requirements   established   pursuant  to  such   agreements,   legislation  and
regulations,  and the  material  furnished to Lucent will be able to be imported
and used  lawfully  (and  without  additional  taxes  associated  with  ODCs not
reported  to Lucent by  BroadBand  as set forth in this  clause)  under all such
agreements,  legislation  and  requirements.  BroadBand also warrants that it is
currently reducing,  or if BroadBand is not the manufacturer of the material, is
currently causing the manufacturing vendor to reduce and will, in an expeditious
manner, eliminate, or, as


                                                                         Page 17


<PAGE>


applicable,  have  its  manufacturing  vendor  eliminate  the use of ODCs in the
manufacture of the material.

If the  material  furnished by BroadBand  under this  Agreement is  manufactured
outside the United States,  BroadBand  shall,  upon execution of this Agreement,
and at any time that new  products  are added to this  Agreement  or changes are
made to the material furnished under this Agreement,  complete,  sign and return
to Lucent the attached ODC Content Certification.  The ODC Content Certification
must be  signed  by  BroadBand's  facility  manager,  corporate  officer  or his
delegate.

The term "ODC content" on the ODC Content  Certification  means the total pounds
of ODC used directly in the manufacture of each unit of material.  This includes
all ODCs used in the manufacturing and assembly operations for the material plus
all  ODCs  used by  BroadBand's  vendors  and any  other  vendors  in  producing
components or other products incorporated into the material sold to Lucent.

BroadBand  is  responsible  to  obtain  information  on the ODC  content  of all
components  and other  products  acquired to  manufacture  the  material  and to
incorporate  such  information  into the total ODC  content  reported to Lucent;
provided  however,  that  BroadBand  should not include in the ODC content those
components  or other  products  which are  manufactured  in the  United  States.
BroadBand hereby warrants to Lucent that all information  furnished by BroadBand
on the ODC Content  Certification  is complete  and accurate and that Lucent may
rely on such information for any purpose, including but not limited to providing
reports to government  agencies or otherwise  complying  with  applicable  laws.
BroadBand  shall  defend,  indemnify  and hold  Lucent  harmless of and from any
claims,  demands,  suits, judgments,  liabilities,  fines, penalties,  costs and
expenses  (including  additional  ODC taxes as provided for in paragraph  one of
this clause and  reasonable  attorney's  fees) which  Lucent may incur under any
applicable federal,  state, or local laws or international  agreements,  and any
and all  amendments  thereto  by  reason  of  Lucent's  use of  reliance  on the
information furnished to Lucent by BroadBand on the ODC Content Certification or
by reason of BroadBand's  breach of this clause.  BroadBand shall cooperate with
Lucent in responding to any inquiry  concerning  the use of ODCs to  manufacture
the material or components  thereof and to execute without additional charge any
documents reasonably required to certify the absence or quantity of ODCs used to
manufacture the material or components thereof.

35.0  PACKING,  LABELING  AND  SERIALIZATION  -  Material  purchased,  repaired,
replaced  or  refurbished  under this  Agreement  shall be packed,  labeled  and
serialized by BroadBand at no additional charge in accordance with the packaging
standards agreed in the applicable  Product Letter.  In developing the packaging
standards,  the  representatives  of the  Parties  will  consider  OEMPS No. 101
"Packing and Shipping  Requirements,"  X-20587  "Specification  Requirements for
Package Content  Identification  Label," and KS-23490  "Product Bar Code, Serial
and Comcode Label".

36.0 PAYMENT TERMS - Invoices shall be paid in accordance with the terms in this
Agreement,  and due dates for payment shall be computed from the date of receipt
of invoices by Lucent.


                                                                         Page 18


<PAGE>


37.0  PRODUCT  CONFORMANCE  REVIEWS  - All  Material  is  subject  to a  Product
Conformance Review ("Review") prior to shipment. BroadBand shall notify Lucent's
designated  quality  inspection  organization  when  Material  is ready for such
Review. BroadBand may ship Material without a Review but Lucent may perform such
Review prior to shipment by giving  BroadBand  notice to that  effect,  in which
event BroadBand shall notify Lucent's designated quality inspection organization
when material is ready for such Review.  BroadBand will provide, without charge,
any production testing facilities and personnel required to perform or assist in
the Review as specified in the applicable Quality Program Specification or other
quality  specification  provided under this Agreement or order. Lucent's Reviews
as set forth  above may only be waived by  written  notification  from  Lucent's
designated quality inspection organization.

Any  major  failure,  detected  in  Lucent's  acceptance  inspection,  shall  be
considered as Dead on Arrival (DOA) which exceeds the percentages set forth in a
purchase  order  or  Product  Letter  for  functional  failures  and  for  total
(functional and visual/mechanical)  defects in the material delivered in any one
month interval.  DOA values (AOQL) specified in this Article shall be consistent
with the AQL levels agreed to for the material.

38.0 REJECTIONS - If Lucent rejects any or all of the Material not conforming to
Specifications  and/or  drawings  covered  by this  Agreement,  Lucent  may,  in
addition to all its other rights and remedies at law or equity,  exercise one or
more of the following remedies:  (1) return rejected material for full credit at
the price charged plus transportation charges from BroadBand's plant and return;
or (2) accept a conforming part of any shipment;  or (3) have rejected  material
replaced by BroadBand at the purchase price stipulated in this Agreement. Should
Lucent  select  option  (1),  it  will  receive  credit  for  the  Manufacturing
Absorption  associated with the rejected  Material.  If the Material rejected is
all or  part  of the  last  scheduled  shipment  of that  type  of  Material  by
BroadBand,  Lucent shall return the Material to BroadBand and allow  BroadBand a
reasonable  opportunity to repair and re-deliver the Material before  exercising
any other remedy.

39.0 REPAIRS NOT COVERED UNDER WARRANTY - In addition to repairs provided for in
the WARRANTY  clause,  BroadBand  shall provide  repair  service on all Material
ordered under this  Agreement  during the term of this  Agreement and until five
(5) years after the last delivery of the related Material by BroadBand. Material
to be repaired  under this clause will be returned to a location  designated  by
BroadBand,  and, unless otherwise agreed upon by BroadBand and Lucent, BroadBand
shall ship the repaired Material which meets the Specifications set forth in the
SPECIFICATIONS  OR DRAWINGS clause and all other  Specifications  within fifteen
(15) calendar days of receipt of the defective or non-conforming  Material. With
the  concurrence  and  scheduling of Lucent,  repair may be made by BroadBand on
site.

     If Material is returned  to  BroadBand  for repair as provided  for in this
clause and is determined to be beyond repair,  BroadBand shall so notify Lucent.
If requested by Lucent, BroadBand will sell to Lucent a replacement at the price
set forth in  BroadBand's  then current  agreement with Lucent for said Material
or, if no such agreement exists, at a price agreed upon by BroadBand and Lucent.
If the  parties  fail to agree  on a  price,  the  price  shall be a  reasonably
competitive  price  for such  Material  at the time for  delivery.  Further,  if
requested by Lucent,


                                                                         Page 19

BroadBand shall take the necessary steps to dispose of the unrepairable Material
and pay to Lucent the salvage value, if any.

     Replacement  and repaired  Material  shall be warranted as set forth in the
WARRANTY clause.

     This  Agreement does not grant  BroadBand an exclusive  privilege to repair
any or all of the Material  purchased  under this Agreement for which Lucent may
require  repair;  and Lucent may perform the repairs or contract with others for
these  services.  In addition,  BroadBand  authorizes  Lucent and any  qualified
repairer  with whom  Lucent  may  contract  to perform  repairs on all  Material
purchased under this Agreement.

     All  transportation  costs of and in  transit  risk of loss and  damage  to
Material  returned to  BroadBand  for repair  under this clause will be borne by
Lucent and all transportation costs of and in transit risk of loss and damage to
such  repaired  or  replacement  Material  returned  to Lucent  will be borne by
Lucent.

complete  inspection  within five (5) working  days,  BroadBand  may deliver its
invoice to Lucent for payment.

45.0  SURVIVAL  OF  OBLIGATIONS  - The  obligations  of the  parties  under this

defined as a hazardous or toxic substance or material under applicable  federal,
state  or  local  law,  ordinance,   rule,   regulation  or  order  (hereinafter
collectively  referred to as "law" or "laws"),  and presents no abnormal hazards
to persons or the environment.  BroadBand also warrants that it has no knowledge
of any federal,  state or local law, that prohibits the disposal of the material
as  normal  refuse  without  special  precautions  except  as  expressly  stated
elsewhere in this Agreement. BroadBand also warrants that where required by law,
all material  furnished  by  BroadBand  is either on the EPA Chemical  Inventory
compiled  under  Section 8 (a) of the Toxic  Substance  Control  Act,  or is the
subject  of an  EPA-approved  pre  manufacture  notice  under 40 CFR  Part  720.
BroadBand  further  warrants that all material  furnished by BroadBand  complies
with all use restrictions, labeling requirements and all other health and safety

regulations promulgated thereunder.

     BroadBand shall defend, indemnify and hold Lucent harmless for any expenses
(including,   but  not  limited  to,  the  cost  of  substitute  material,  less
accumulated  depreciation)  that  Lucent  may incur by  reason of the  recall or
prohibition against continued use or disposal of material furnished by BroadBand
as described in its Agreement  whether such recall or prohibition is directed by
BroadBand  or occurs  under  compulsion  of law.  Lucent  shall  cooperate  with
BroadBand to  facilitate  and minimize the expense of any recall or  prohibition
against use or disposal of material directed by BroadBand or under compulsion of
law.

     BroadBand  further shall defend,  indemnify and hold Lucent harmless of and
from any claims,  demands,  suits,  judgments,  liabilities,  costs and expenses

50.0 TERMINATION -

a)   Either  party may  terminate  this  Agreement  upon  sixty  (60) days prior
     written  notice  to the other  party for  failure  of such  other  party to
     fulfill any of its material obligations  hereunder;  provided,  however, if
     during the period of such notice the other party shall have  remedied  such
     failure, this Agreement shall continue in full force and effect as it would
     have had such failure not occurred.

b)   Should  Material  experience  rejection  rates by  Lucent  beyond  the norm
     established in a Product  Letter,  Lucent may terminate this Agreement with
     respect  to such  Material.  The  effect of such a  termination  will be to
     proportionately   reduce  Lucent's  obligation   respecting   Manufacturing
     Absorption set forth in Clause 7.0. The proportionate  reduction associated
     with  any  such  rejection  shall  be  calculated  in  accordance  with the
     following:

     1.   Each item of Material  will be assigned a  weighting  in the  relevant
          Product  Letter.   To  do  so,  the  expected  annual   percentage  of
          Manufacturing   Absorption   will  be  identified   and  the  expected
          percentage  of the term of this  Agreement  that the Material  will be
          manufactured by BroadBand will be defined.  The weight assigned to the
          Material  will  be  calculated  by  multiplying  the  two  percentages
          together. ************************************************************
          **********************************************************************

     2.   BroadBand will have the period of time  identified in a Product Letter
          for that  Material  to  achieve  the  quality  level  set forth in the
          Product Letter.

     3.   If  BroadBand  is unable to achieve the quality  level within the time
          period or to maintain  the quality  level (with  respect to the reject
          rate norm),  Lucent may terminate its obligation for that Material and
          receive   credit   for  the   associated   Manufacturing   Absorption.
          **********************************************************************
          **********************************************************************

     Should the cumulative reductions of the Manufacturing Absorption obligation
     pursuant  to this  clause  reach  nine  million  dollars,  Lucent  shall be
     entitled  to  terminate  this  Agreement  with  no  further  obligation  to
     BroadBand.

c)   In  the  event  of a  Change  in  Control  of  BroadBand  or  a  reasonable
     expectation  of a Change in Control of BroadBand,  BroadBand  shall provide
     notice to Lucent of such actual or expected  Change in Control event within
     ten (10) business days of the  knowledge or reasonable  expectation  of the
     Change in Control  event.  Upon the effective  date of a Change in Control,
     Lucent shall have the right to terminate this Agreement by giving BroadBand
     written  notice of its  intention  to  terminate  at least ninety (90) days
     prior to the  termination  date specified in the  termination  notice.  The
     Parties understand and agree that if Lucent elects to exercise its


                                                                         Page 23

     right to terminate,  then such  termination  shall apply on a going forward
     basis, but shall not apply to past purchase orders that are completed or to
     current purchase orders that are firm and binding commitments of Lucent.

A Change  in  Control  occurs  upon any one of the  following  circumstances  or
events:

(i)   The  stockholders  of a Party  ("Acquired  Party")  approve a transaction,
      including,   without  limitation,   a  merger  or  consolidation  (however
      denominated  or  effectuated),   with  an  Acquiror,   including,  without
      limitation, a merger or consolidation,  or series of transactions with the
      same Acquiror  ("Combination"),  and immediately after such transaction(s)
      less  than  60% of  the  combined  voting  power  of the  then-outstanding
      securities  of the  Acquired  Party or the  Acquiror,  will be held in the
      aggregate by the holders of securities entitled, immediately prior to such
      Combination,  to  vote  generally  in the  election  of  directors  of the
      Acquired Party ("Voting Securities");

(ii)  The stockholders of the Acquired Party approve the sale or transfer of all
      or substantially all of its assets to any other Person or entity, and less
      than  60% of the  combined  voting  power of the  then-outstanding  Voting
      Securities of such Acquiror  immediately  after such  transaction  will be
      held in the  aggregate  by the  holders  of the Voting  Securities  of the
      Acquired Party immediately prior to such sale;

(iii) An  Acquiror  acquires  in  one or a  series  of  transactions  beneficial
      ownership of more than 40% of the outstanding  shares of Voting Securities
      of a Party;

(iv)  The  stockholders  of a Party  approve a plan of complete  liquidation  or
      dissolution of the Party;

(v)   Any Acquiror obtains direct or indirect Control (as herein defined) over a
      party and, in Lucent's  reasonable  judgment,  such  Control may  threaten
      Lucent's  interests.  For  the  purposes  of  this  subsection,  the  term
      "Control" shall mean the possession directly or indirectly of the power to
      direct or cause the  direction of the  management  or policies of a Party,
      whether  through  the  ability to exercise  voting  power,  by contract or
      otherwise;

(vi)  At any time, Continuing Directors (as herein defined) shall not constitute
      at least 50% of the members of the Board ("Continuing  Director" means (i)
      each individual,  who has been a director of the Party for at least twelve
      (12) consecutive  months before such time and (ii) each individual who was
      nominated  or elected to be a director of the Party by at least a majority
      of the Continuing  Directors at the time of such  nomination or election);
      or

(vii) Any other  transaction  which has the  effect of causing  the  substantive
      changes  in  the  Acquired  Party   described  in  any  of  the  preceding
      paragraphs.

      For the  purposes  of this  Section,  the term  "Acquiror"  shall mean one
      person or entity,  or two or more persons and/or  entities  constituting a
      "group" for purposes of the Securities Exchange Act of 1934, as amended.


                                                                         Page 24

Specifications,  drawings  and  samples  set  forth  in  this  Agreement.  These
warranties  extend for  ***********  from the date of delivery to Lucent  unless
otherwise agreed by the Parties in a Product Letter or other writing.

      If Material furnished contains one or more manufacturer's  warranties that
are assignable,  BroadBand  hereby assigns such warranties to Lucent.  BroadBand
warrants that at the time of delivery to Lucent such  Material  shall be free of
any security interest or any other lien or any other encumbrance whatsoever. All
warranties shall survive inspection, acceptance and payment.

      Defective or non-conforming  Material will, at BroadBand's option,  either
be returned to BroadBand for repair or replacement,  at no cost to Lucent,  with
risk of  in-transit  loss and damage  borne by  BroadBand  and  freight  paid by
BroadBand,  or be  repaired or  replaced  by  BroadBand  on Lucent's or Lucent's
customer's  site or  another  site  designated  by Lucent at no cost to  Lucent.
Unless otherwise  agreed upon by BroadBand and Lucent,  BroadBand shall complete
repairs  and ship the  repaired  Material  within 10 working  days of receipt of
defective or non-conforming  Material,  or at Lucent's option,  ship replacement
Material within 10 working days after verbal  notification is given BroadBand by
Lucent.  BroadBand  shall bear the risk of in-transit  loss and damage and shall
prepay and bear that cost of freight  for  shipments  to Lucent of  repaired  or
replaced Material.

      If Material  returned to  BroadBand  is  determined  to be beyond  repair,
BroadBand  shall promptly so notify Lucent and,  unless  otherwise  agreed to in
writing by BroadBand and Lucent, ship replacement Material without charge within
ten (10) days of such notification.

      Replacement  Material  shall  be  warranted  as set  forth  above  in this
WARRANTY clause. Any Material which is repaired, modified, or otherwise serviced
by  BroadBand  shall be warranted  as provided in this  WARRANTY  clause for the
remainder of the warranty  period (based upon the date repair,  modification  or
other service is completed and accepted by Lucent) or ninety (90) days after the
Material is returned to Lucent, whichever is later.

      LUCENT'S SOLE AND EXCLUSIVE  REMEDY FOR BREACH OF A WARRANTY  CONTAINED IN
THIS ARTICLE SHALL BE  BROADBAND'S  OBLIGATION TO REPAIR,  REPLACE,  CREDIT,  OR
REFUND AS SET FORTH IN THIS AGREEMENT,  EXCEPT THAT THE FOREGOING  LIMITATION ON
REMEDIES  FOR BREACHES OF  WARRANTIES  SHALL NOT LIMIT THE REMEDIES OF LUCENT OR
ANY OTHER  CAUSE OF ACTION FOR  PERSONAL  INJURY  INCLUDING  DEATH AND  TANGIBLE
PROPERTY DAMAGE CLAIMS.

PURCHASE PRICE, AT BROADBAND'S OPTION OF THE ITEM OR SERVICE THAT DIRECTLY GIVES

writing of any written  authorization  issued by the U.S. Department of Commerce
office of export  licensing to export or reexport any such items  referenced  in

all products,  including packaging and packaging components,  provided to Lucent

any patent,  copyright,  trademark or trade secret right, or other  intellectual
property  right,  private right, or any other  proprietary or personal  interest
related to the Specifications for the Material, and (2) related by circumstances
to the existence of this Agreement or performance  under or in  contemplation of
it (an  Infringement  Claim).  Lucent or BroadBand (at Lucent's  request)  shall
defend  or  settle,  at  Lucent's  expense  any  demand,  action  or suit on any
Infringement Claim for which Lucent is indemnitor under the preceding provisions
and each  shall  timely  notify  the other of any  assertion  against  it of any
Infringement  Claim  and  shall  cooperate  in good  faith  with  the  other  to
facilitate the defense of any such Claim.  Broadband shall  similarly  indemnify
and save harmless Lucent from any Infringement Claim associated with BroadBand's
manufacturing or other processes.

55.0  SEVERABILITY - If any of the provisions of this Agreement shall be invalid
or unenforceable,  such invalidity or  unenforceability  shall not invalidate or
render  unenforceable  this entire  Agreement,  but rather this entire Agreement
shall be construed as if not containing the


                                                                         Page 26

particular invalid or unenforceable provision or provisions,  and the rights and
obligations of the parties shall be construed and enforced accordingly.

56.0  CHOICE  OF LAW - This  Agreement  and all  transactions  under it shall be
governed  by the laws of the State of New  Jersey  excluding  its choice of laws
rules  and  excluding  the  Convention  for the  International  Sale  of  Goods.
BroadBand agrees to submit to the jurisdiction of any court wherein an action is
commenced  against  Lucent  based on a claim for which  BroadBand  has agreed to
indemnify Lucent under this Agreement.

57.0 DISPUTE RESOLUTION (a) The following  procedures shall apply to any dispute
or disagreement  between the Parties or any of their Related Parties (i.e., such
Party's  wholly  owned  subsidiaries,   and  the  respective  divisions,  heirs,
successors and assigns of such Party and its wholly owned subsidiaries)  arising
out of this Agreement.

      (b) First:

            (i) either  Party may give written  notification  of such dispute or
      disagreement to the other Party and

            (ii) the Parties shall  communicate  with each other promptly with a
      view to  resolving  such dispute or  disagreement  within 21 days (or such
      extended  period as the Parties  agree is  appropriate  in any case) after
      such written notification is given.

      (c) The giving of any notice  regarding any dispute or disagreement  under
this  Section  10.1  shall  toll  the  running  of all  applicable  statutes  of
limitation until the later of (i) 90 days following the giving of such notice or
(ii) 30 days  following  the  termination  of  discussions  between  the Parties
concerning such dispute or disagreement.

      (d)  Second,  if at the end of the 21 day  period  referenced  in  Section
57.0(b)(as  it may be  extended)  such  dispute  or  disagreement  has not  been
resolved  to the  satisfaction  of both  parties,  either  Party may  request in
writing  that  such  dispute  or  disagreement  be the  subject  of  non-binding
mediation.  Following  such request,  the Parties  shall  endeavor in good faith
promptly to identify a single person (who shall be a person with  experience and
good  reputation)  who shall  assist the Parties in  discussing  such dispute or
disagreement  and  in  attempting  to  reach  a  mutually   acceptable  business
resolution.  Such  mediation  process  shall  terminate  not later  than 30 days
following  the  request  therefor  (or such  extended  or shorter  period as the
Parties agree is  appropriate).  All applicable  statutes of limitation shall be
tolled during the period of mediation.

      (e)  Third,  if at the  end of the 30 day  period  referenced  in  Section
57.0(d) (as it may be extended or shortened)  such dispute or  disagreement  has
not been  resolved  to the  satisfaction  of both  parties,  either  Party  (the
"complainant")  may commence binding  arbitration by giving the other Party (the
"respondent")  notice in writing  (the  "initiating  notice")  setting  forth in
reasonable  detail the nature of its claim and the relief requested stating that
the complainant is invoking the procedures set forth in this Section 57.0(e) and
(f) and naming the  complainant's  representative  on the Arbitration  Panel (as
defined  below).  Within  21  days  of  receipt  of an  initiating  notice,  the
respondent shall give the complainant notice in writing (the "response") setting
forth in


                                                                         Page 27


<PAGE>


reasonable detail: (1) the basis of its response to the claim; (2) the nature of
any  counterclaim  it has against the  complainant  arising from the same set of
facts and  circumstances  that gave rise to the  original  claim;  (3) any other
counterclaim  that Party wishes to bring at that time (although the Party has no
obligation to bring such  counterclaims at that time); (4) the relief requested;
and (5) naming the respondent's representative on the Arbitration Panel. The two
representatives  shall select a third person who is mutually acceptable to them.
If the  representatives  fail  to  make  such  selection  within  21  days,  the
complainant and the respondent shall each replace its representative  with a new
representative  and the new  representatives  shall be subject to the  preceding
sentence  and this  sentence.  Once a third  person  is  selected,  such  person
together with the  representatives  of the complainant and the respondent  shall
form the Arbitration  Panel. The date upon which the Arbitration Panel is formed
shall be the "Commencement Date".

      (f) The  Arbitration  Panel shall  conduct  proceedings  to determine  the
merits under applicable law of the claims set forth in the initiating notice and
the  response.  The  proceedings  shall be  administered  by  JAMS/Endispute  in
accordance with its Comprehensive  Arbitration Rules and Procedures in effect as
of the Effective Date, subject to the following additional rules:

            (i) the proceedings shall take place in New York City;

            (ii)  the   Arbitration   Panel   (including,   if  necessary,   any
      replacement(s) to the Arbitration Panel) shall be selected as set forth in
      Section 57.0(e);

            (iii) the available relief shall include damages,  injunctive relief
      and equitable  relief to the extent allowed under the applicable law, this
      Agreement and any other agreement between the parties;

            (iv) the parties  shall  attempt in good faith  promptly to agree on
      the nature and extent of any discovery in connection with the arbitration,
      provided  that,  in the  absence  of such  agreement,  discovery  shall be
      governed  by   JAMS/Endispute's   Comprehensive   Arbitration   Rules  and
      Procedures.  In addition, the applicable law with respect to privilege and
      other  protections  from  disclosure,  including the work product doctrine
      shall apply;

            (v) the final decision of the Arbitration  Panel (the "Award") shall
      be issued within six months of the Commencement Date (the date of issuance
      of the Award  being the  "Award  Date") and must be joined by at least two
      members of the Arbitration Panel;

            (vi)  each  party  to the  proceedings  shall  pay its own  costs in
      connection with the  proceedings,  including the costs and expenses of its
      representative  on the  Arbitration  Panel,  and the  parties  shall share
      equally  the other  costs of the  proceedings,  including  the fees of the
      third member of the Arbitration  Panel,  except that the prevailing  party
      shall be entitled to recover its  attorneys'  fees incurred in prosecution
      thereof.

      (g) In accordance with the Federal Arbitration Act, 9 U.S.C. ss.1 et seq.,
the Award shall be final and binding and judgment  thereon may be entered by any
state or federal court having jurisdiction thereof.


                                                                         Page 28


<PAGE>


      (h) Nothing in this Section  57.0 shall be  construed  to preclude  either
party from seeking  injunctive  relief in a court of competent  jurisdiction  to
prevent imminent  irreparable harm. The dispute resolution  procedures set forth
herein shall be stayed pending  disposition of any  application for such relief.
The Parties agree that a court of competent jurisdiction may consider the merits
of any claim that is  subject to the  dispute  resolution  procedures  set forth
herein to the  extent  necessary  to resolve  any  permissible  application  for
injunctive relief.

provision of the United States Bankruptcy Code, voluntary or involuntary,  by or
against either party, and this Agreement has not been terminated, the non-debtor
party may file a request with the bankruptcy  court to have the court set a date
within sixty (60) days after the  commencement  of the case, by which the debtor
party will assume or reject this Agreement, and the debtor party shall cooperate
and take whatever  steps are necessary to assume or reject the Agreement by such
date. If a bankruptcy  proceeding results in a Change In Control, the provisions
in this Agreement pertaining to Change In Control shall govern.

customs laws,  statutes,  and  regulations,  and in support of this  assistance,
BroadBand agrees to follow Lucent's directives, if any, which may be attached to
and made part of this Agreement.

62.0  RELATIONSHIP  OF PARTIES - The  relationship of the Parties as established
under this  Agreement  shall be and remain one of independent  contractors,  and
neither Party will at any time or in any way represent itself as being a dealer,
agent or other  representative  of the  other  Party or as having  authority  to
assume or create  obligations or act in any manner on behalf of the other Party.
Further,  it is understood and agreed that the Parties to this Agreement are not
partners or joint venturers.

63.0  INDEPENDENT  AGREEMENT - Breach by a Party of any other agreement  between
the Parties  shall not  constitute a breach of this  Agreement,  unless the same
conduct independently  breaches this Agreement. A breach of this Agreement shall
not constitute a breach


                                                                         Page 29

each of which  shall be  deemed an  original,  but all of which  together  shall
constitute one and the same instrument.

                             MANUFACTURING AGREEMENT

                      ENGINEERING CHANGE CONTROL PROCEDURES

      "Product   Changes"  shall  be   administered   in  accordance  with  Bell
Communications  Research  document GR 209 CORE,  Issue 2, January  1996,  titled
"Generic  Requirements for Product Change Notices," which is incorporated herein
by reference.

      Supplier may make changes to MATERIAL, modify drawings, or make changes to
manufacturing   specifications,   provided   the  changes,   modifications,   or
substitutions DO NOT have an impact on the performance,  reliability, Form, Fit,
or Function of the MATERIAL  without  prior  notification  to Company.  Supplier
shall  maintain  written  records of all such  changes,  and make these  records
available for Company's review upon request.

      For such changes or modifications  which DO have an impact on performance,
reliability, Form, Fit, or Function, Supplier shall identify each such change or
modification in accordance with the classifications  contained in the above Bell
Communications  Research document via a Product Change  Notification (PCN) form.
The  Company  shall   immediately   acknowledge   receipt  of  the  PCN  to  the
address/contact  as stated on the PCN form and shall have thirty  (30)  calendar
days to advise Supplier if the proposed change or modification is  unacceptable.
If Company  notifies  Supplier as required  herein,  that the proposed change or
modification  is  unacceptable,  Supplier  shall not  implement  such  change or
modification. Company may reject any MATERIAL offered by Supplier which has been
changed or modified in a manner unacceptable to Company.

      If Company has not notified  Supplier that the change or  modification  is
unacceptable  within thirty (30) calendar days following  issuance of the Change
Notification,  Supplier shall  implement the change or modification as described
in the Change Notification.

      If during the  review of a proposed  PCN,  which has a  classification  of
either A or AC,  issued by Supplier  during the Warranty  period of the affected
MATERIAL,  the Company determines that implementation of the PRODUCT CHANGE will
cause the Company to incur "unreasonable  expenses" such as, but not limited to,
expenses  resulting  from  escorting  Supplier's  personnel to numerous  Company
locations  containing  affected MATERIAL or repeated product changes to the same
item of MATERIAL within a one (1) year time period,  the Company shall so notify
Supplier, in writing, prior to the implementation of such PRODUCT CHANGE.

      Upon such  notification,  the Company and Supplier shall jointly determine
the implementation  procedure which will utilize the Supplier's and/or Company's
personnel in the most cost effective manner.

      If  Supplier  and  the  Company  conclude  the  agreed  to  implementation
procedure will probably cause the Company to incur "unreasonable  expenses", the
Company and Supplier shall jointly  determine the likely extent of such expenses
and agree, in writing,  to a "not to exceed"  estimate for such expenses.  In no
event shall such estimate  exceed the Company's  purchase price for the MATERIAL
to be changed.  The Company shall track and record all such expenses  associated
with the PRODUCT  CHANGE.  Upon  completion  of its efforts,  the Company  shall
submit to Supplier,  for reimbursement by Supplier,  an invoice of the Company's
"unreasonable expenses" within forty-five (45) calendar days after the Company's
receipt of such invoice.

      Issuing a Class A or AC product Change  Notification  shall not constitute
an  agreement   to  provide  such  a  change,   but  shall  be  construed  as  a
recommendation by the Supplier that the change is absolutely necessary.

("Parts") which are functionally equivalent and identical in Form, Fit and
Function to the Material covered by this Agreement. The price for the Material
and Parts shall be the price set forth in Supplier's then current agreement with
Company for said Material or Parts or, if no such agreement exists, a price
agreed upon by Company and Supplier. If the Parties fail to agree on a price,
the price shall be a reasonably competitive price for said Material or Parts at
the time for delivery. The Material and Parts shall be warranted as set forth in
Section 4.1.

                              2. Orders and Payment

2.1 INVOICING FOR GOODS - Supplier shall: (1) render an original invoice, or as
otherwise specified in this Agreement, which shows the order number, through

                                       3
<PAGE>

are only provided to assist Supplier in planning its manufacturing activities
and they do not commit or bind Company to purchase or the Supplier to supply any
Materials, or any quantity of Materials. A forecast only becomes binding upon
the Parties when a Purchase Order, as set forth below, is forwarded by Company
to Supplier and Supplier duly accepts it and the agreed upon delivery schedule
for such Purchase Order is within ninety (90) days, except that such 90-day
forecast commitment period may be altered by mutual agreement of the Parties for
particular Material described in Product Letters. At such time, any changes to
the volume of Materials committed to by the Parties shall be governed by
Sections 2.7, 2.8 and 2.9 below.

2.7 PURCHASE ORDERS - Purchase orders issued under this Agreement shall be sent
to the following address:

         BroadBand Technologies, Inc.
         P.O. Box 13737

         ATTN: Customer Logistics Department

         This Agreement shall incorporate the typed or written provisions on
Company's orders issued pursuant to this Agreement. Printed provisions on
Company's orders (except as specified otherwise in this Agreement), boilerplate
provisions in electronic orders and all provisions on Supplier's forms shall be
deemed deleted. Estimates or forecasts furnished by Company shall not constitute
commitments, except as otherwise set forth in this Agreement.

         Purchase orders shall specify: (a) description of Material, inclusive
of any numerical/alphabetical identification referenced in the price list in
this Agreement, (b) delivery date, (c) applicable price, (d) location to which
the Material is to be shipped and (e) location to which invoices shall be sent
for payment.

         Orders consistent with the Company forecast and requesting delivery
more than ninety (90) days (or the alternate forecast commitment period
specified for particular Material in the applicable Product Letter) from the
date the order is received by Supplier will be accepted or rejected by Supplier
in writing within five (5) business days from receipt of the order. Orders
requesting delivery in less than ninety days and which exceed the forecast shall
be deemed accepted unless Supplier provides written notice to the contrary
within ten (10) business days from receipt of the order.

         Company may at any time subsequent to the issuance of a purchase order
under this Agreement change the purchase order quantity at no charge in
accordance with the schedule below:

         Number of Days Prior to    Allowable Increase/Decrease
         Scheduled Shipment Date        (% of P.O. Quantity)

                                       4
<PAGE>


         0-90 (or 0-alternate forecast       0%      0%
         commitment period)

         91-greater (or alternate forecast  100%   100%
         commitment period-greater)

Company will make reasonable efforts to provide forecasts and purchase orders
for Material that avoid sharp increases or decreases in production.

2.8 SHIPPING - Supplier shall: (1) ship the Material covered by this Agreement
or order complete unless instructed otherwise; (2) ship to the destination
designated in the Agreement or order; (3) ship according to routing instructions
given by Company; (4) refer to this Agreement and the order number on all
subordinate documents; (5) enclose a packing memorandum with each shipment and,
when more than one package is shipped, identify the package containing the
memorandum; and (6) mark the Agreement and order number on all packages and
shipping papers. Adequate protective packing shall be furnished at no additional
charge. Shipping and routing instructions may be furnished or altered by Company
without a writing. All deliveries will be FOB Supplier's factory. If Supplier
does not comply with Company's written shipping or routing instructions,
Supplier authorizes Company to deduct from any invoice of Supplier (or to charge
back to Supplier), any increased costs incurred by Company as a result of
Supplier's noncompliance.

2.9 SHIPPING INTERVAL - The delivery schedule applicable to each purchase order
will be set forth in the purchase order.

         If Supplier does not deliver by the delivery date specified in the
applicable purchase order, then in addition to all other rights and remedies at
law or equity or otherwise, and without any liability or obligation of Company,
Company shall have the right to: (a) cancel such purchase order following the
expiration of a five (5) business day grace period, or (b) extend such delivery
date to a later date, subject, however, to the right to cancel as in (a)
preceding if delivery is not made or performance is not completed on or before
such extended delivery date. If Company elects to extend such delivery date,
Supplier shall absorb the difference between the charges to ship normal
transportation and the charges to ship premium overnight.

         If a purchase order is canceled by Company pursuant to the above,
Company shall have the right to retain or return any or all material received by
or paid for by Company under such purchase order. Within fifteen (15) days of
Supplier's receipt of returned material, Supplier shall reimburse Company for
the reasonable costs of shipping the material returned to Supplier and for any
amounts, including shipping costs, previously paid by Company for the Material.
Company shall pay for any Material it retains at the prices set forth in the
applicable Product Letters, less applicable discounts which shall be applied on
the basis of the quantity specified in the purchase order.

                                       5
<PAGE>

         If, during the course of this Agreement, Supplier determines that
Supplier will no longer be able to ship within the above interval, Supplier
shall immediately notify Company's buyer to that effect. Supplier shall also
notify Company's buyer, as soon as it becomes apparent, if Supplier is unable to
meet the delivery date for an order. However, nothing contained in this
paragraph shall waive Company's rights as set forth above in this Section.

2.10 TITLE AND RISK OF LOSS - Title and risk of loss and damage to Material
purchased by Company under this Agreement shall vest in Company when the
Material has been delivered at the FOB point. If this Agreement or an order
issued pursuant to this Agreement calls for additional services to be performed
after delivery, Supplier shall retain title and risk of loss and damage to the
Material until the additional services have been performed. If Supplier is
authorized to invoice Company for Material upon shipment or prior to the
performance of additional services, title to Material shall vest in Company upon
payment of the invoice, but risk of loss and damage shall pass to Company when
the additional services have been performed.

2.11 TITLE TO MATERIAL FURNISHED BY COMPANY -In the event that Company provides
components to Supplier for use in Material ("Components"), or provides Supplier
with capital equipment, such as a test facility ("Capital Goods") Supplier
acknowledges and agrees that Company has and shall have at all times all right,
title and interest in Components or Capital Goods furnished directly or
indirectly to Supplier by Company under this Agreement. Supplier shall, within
ten (10) days of receipt of the Components or Capital Goods, notify Company in
writing of any claims for quantity variation or quality problems in the
Components or Capital Goods furnished to Supplier. Supplier assumes
responsibility for any loss or damage to such Components or Capital Goods and
shall be liable for the full and actual value of the Components or Capital
Goods. Supplier shall store the Components or Capital Goods safely, indoors in
protected areas approved by Company at Supplier's facility. If Supplier removes
all or any part of the Components or Capital Goods from one building to another,
Supplier shall continue to be responsible for loss and damage and Supplier shall
give Company at least ten (10) business days advance notice, in writing, of the
removal except when the removal is required during Supplier's manufacturing
process or to protect the Components or Capital Goods from damage or loss.

         Company may inspect, inventory and authenticate the account of the
Components or Capital Goods during Supplier's normal business hours. Supplier
shall provide Company access to the premises wherein all such Components or
Capital Goods are located. The Components shall be kept segregated in an area
marked "PROPERTY OF LUCENT TECHNOLOGIES". For purposes of this Section, the term
" Lucent Technologies " shall be deemed to mean Lucent Technologies Inc. or the
Lucent Technologies Inc. affiliated or associated company which owns the
Components or Capital Goods, as applicable.

                                       6
<PAGE>

         Supplier shall use the Components or Capital Goods only in the
manufacture of Material furnished to Company or otherwise in performing under
this Agreement.

         Supplier shall not allow any security interest, lien, tax lien or other
encumbrance (collectively referred to as "Encumbrance") to be placed on any
Components or Capital Goods. Supplier shall give Company immediate written
notice should any third party attempt to place or place an Encumbrance on such
Components or Capital Goods. Supplier shall indemnify and hold Company harmless
from any such Encumbrance. Supplier shall, at Company's request, promptly
execute a "protective notice" UCC-1 form and all other documents reasonably
necessary to enable Company to protect its interest in such Components or
Capital Goods. The Parties agree that this Agreement shall constitute the
security agreement required by the UCC of the appropriate state.

         The obligations assumed by Supplier with respect to the Components or
Capital Goods are for the protection of Company's property. If Supplier defaults
in carrying out Supplier's obligations under this Agreement, then, at no cost to
Company and upon five (5) working days notice to Supplier, Company may cancel
this Agreement with regard to affected Materials or withdraw all or any part of
the Components or Capital Goods, or both. Supplier shall, at Company's option,
return to Company or hold for Company's disposition any and all of such
Components or Capital Goods (including any scrap produced as a by-product) in
Supplier's possession at (a) the completion of the order, (b) expiration,
cancellation or termination of this Agreement, or (c ) the withdrawal of
Components or Capital Goods, as provided above


                                   3. Services

3.1 SERVICES - Visits by Supplier's representatives or its suppliers'
representatives for inspection, adjustment or other similar purposes in
connection with Material purchased under this Agreement shall for all purposes
be deemed "Work under this Agreement" and shall be at no charge to Company
unless otherwise agreed in writing between the Parties.

3.2 TECHNICAL SUPPORT AND TRAINING - At the time a purchase order is entered
into by the Parties, they shall determine, negotiating in good faith, the level
and extent of technical support appropriate for the Material ordered. However,
the Parties hereby agree that the Company shall be entitled to a mutually agreed
upon level of ongoing technical support, which shall include field service and
assistance, and they further agree that the availability or performance of this
technical support service shall not be construed as altering or affecting
Supplier's obligations as set forth in Section 4.1 or elsewhere provided for in

                     4. Warranty and Limitation of Liability

4.1 WARRANTY - Supplier warrants to Company and Customer, as defined in this
Section, that hardware, including firmware, furnished hereunder will be new,
free from defects in design, material and workmanship and will conform to and
perform in accordance with the Specifications for a period of *********** after
delivery, and that software furnished will conform to and perform in all
material respects with the Specifications for a period of ************* after
delivery; provided, however, that if significant software defects are
discovered, equating to Severity Levels 1 or 2, Company may require a software
fix from Supplier for up to ***************** from delivery.

         If Material furnished contains one or more manufacturer's warranties
that are assignable, Supplier hereby assigns such warranties to Company and
Customers. Supplier warrants that at the time of delivery to Company such
Material shall be free of any security interest or any other lien or any other
encumbrance whatsoever. All warranties shall survive inspection, acceptance and
payment. Different warranty periods may be specified in the applicable Product
Letters.

         Defective or non-conforming Material will, at Supplier's option, either
be returned to Supplier for repair or replacement, at no cost to Company, with
risk of in-transit loss and damage borne by Supplier and freight paid by
Supplier, or be repaired or replaced by Supplier on Company's or Company's
customers' site or another site designated by Company at no cost to Company.
Unless otherwise agreed upon by Supplier and Company, Supplier shall complete
repairs and ship the repaired Material within ten (10) working days of receipt
of defective or non- conforming Material, or at Company's option, ship
replacement Material within ten (10) working days after verbal notification is
given Supplier by Company.

         If Material returned to Supplier or made available to Supplier on site
for repair as provided for in this Section is determined to be beyond repair,
Supplier shall promptly so notify Company and, unless otherwise agreed to in
writing by Supplier and Company, ship replacement Material without charge within
ten (10) days of such notification.

         Replacement Material shall be warranted as set forth above in Section
4.1. Any Material which is repaired, modified, or otherwise serviced by Supplier
shall be warranted as provided in Section 4.1 for the remainder of the warranty
period (based upon the date repair, modification or other service is completed
and accepted by Company) or ninety (90) days after the Material is returned to a
customer of Company, whichever is later.

EXCEPT AS SET FORTH ABOVE, SUPPLIER DISCLAIMS ALL WARRANTIES, EXPRESS AND
IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND/OR FITNESS FOR A PARTICULAR PURPOSE.



                                       8
<PAGE>

4.2 LIMITATION OF LIABILITY - NEITHER PARTY SHALL BE LIABLE FOR ANY INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR FOR LOSS OF PROFITS, REVENUE OR DATA,
WHETHER IN AN ACTION IN CONTRACT, TORT, STRICT LIABILITY, OR OTHERWISE, EVEN IF
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

                                   5. Quality

5.1 EPIDEMIC CONDITION - If, during the term of this Agreement and for five
years after the last shipment date of Material under this Agreement, Company
notifies Supplier that Material shows evidence of an "Epidemic Condition,"
Supplier shall prepare and propose a Corrective Action Plan ("CAP") with respect
to such Material within ten (10) working days of such notification, addressing
implementation and procedure milestones for remedying such Epidemic
Condition(s). An extension of this time-frame is permissible upon mutual written
agreement of the Parties.

         Upon notification of the Epidemic Condition to Supplier, Company shall
have the right to postpone all or part of the shipments of unshipped Material
exhibiting the epidemic condition, by giving written notice of such postponement
to Supplier, pending correction of the Epidemic Condition. Such postponement
shall temporarily relieve Supplier of its shipment liability and Company of its
shipment acceptance liability. Should Supplier not agree to the existence of an
Epidemic Condition or should Company not agree to the CAP, then Company shall
have the right to suspend all or part of its unshipped orders without liability
to Company until such time as a mutually acceptable solution is reached.

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

  (1)    Failure reports or statistical samplings show that four (4) percent or
         more of Material installed or four (4) percent or more of Material
         shipped during any two consecutive months, or four (4) percent or more
         of the Material tracked by Company's Field Quality Engineering contain
         a potential safety hazard (such as personal injury or death, fire,
         explosion, toxic emissions, etc.), or exhibit a highly objectionable
         symptom (such as emissions of smoke, loud noises, deformation of
         housing) or other disconcerting symptoms of this type.

(2)      Reliability plots of relevant data indicate that the Material has
         actual Mean Time Between Failures (MTBF) of less than 80% of the MTBF
         stipulated in the Technical Specification. The MTBF parameter of
         Material is defined as the total operating or power-on time of any
         population under observation ("T"), in hours, divided by the total
         number of critical failures ("n") that have occurred during the
         observed period. A critical failure is defined as a failure to operate
         per the requirements of the Technical Specification. The total
         operating time of a population is the summation of operating time of
         individual units in that



                                       9
<PAGE>

         population. MTBF is expressed as MTBF = T/n. An Epidemic Condition
         shall exist when data derived from populations being tracked confirms
         the condition with 80% confidence.

(3)      Material Dead on Arrival (DOA) failures exceed the Epidemic DOA
         failure rate which is defined as 1.2 x DOA rate specified in the
         applicable Product Letter.

         Only major functional and visual/mechanical/appearance defects are
considered for determining Epidemic Condition. Material can be either sampled
or, at Company's option, 100% audited at Company warehouses, factories or
Company's customers' locations. If Material is sampled, the data must have 80%
or better statistical confidence.

         For the purpose of this Agreement, functional DOA shall be defined as
any Material that during the test, installation or upon its first use fails to
operate as expected or specified. Visual/mechanical/appearance DOA is defined as
any Material containing one or more major defects that would make the Material
unfit for use or installation.

         An Epidemic Condition shall not include failures due to customer
misapplication, utilization of parts not approved by Supplier, or chain failures
induced by internally or externally integrated subassemblies.

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

(a)      Incorporate the remedy in the affected Material in accordance with
         Company's Engineering Change Control procedures as set forth in
         Attachment 2;

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

(c)      Repair and/or replace Material that caused the Epidemic Condition. In
         the event that Company incurs costs due to such repair and/or
         replacement, including but not limited to labor and shipping costs,
         Supplier shall reimburse Company for such reasonable costs. Supplier
         shall bear risk of in transit loss and damage for such repaired and/or
         replaced Material.

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

         If Supplier is unable to develop a mutually agreeable remedy, or does
not adequately take into account the business interests of Company, as
reasonably agreed by the Parties, Company may (1) develop and implement such
remedy and, in such case, reasonable implementation costs and risk of in-transit
loss and damage shall be allocated

between the Parties as set forth in this Section, and/or (2) cancel postponed
orders without liability and return all Material affected by such Epidemic
Condition for full refund, payable by Supplier within thirty (30) days after
receipt of returned Material (with risk of loss or in-transit damage borne by
Supplier).

5.2      INSPECTION, ACCEPTANCE TESTING, AND QUALITY CONTROL STANDARDS

(a)      Ongoing Inspection and Testing. All Material shall be subject, at
         either Supplier's manufacturing facility or at Company premises, to
         further inspection, acceptance testing, and review for conformance to
         ongoing quality control standards as may be established in the
         Specifications.

(b)      Acceptance Inspection and Acceptance Testing. All Material shall be
         subject to acceptance inspection and testing by Company, at Company's
         election, on Supplier's premises, during normal business hours and
         following a reasonable notice to Supplier , on Company's premises, or
         at a location selected by Company (including the premises of any
         customer of Company). When conducted on Supplier's premises by
         Supplier, copies of all documents prepared by Supplier indicating the
         results of such inspection and testing shall be provided to Company at
         Company's request. Inspection and testing at Company's facilities or
         locations designated by Company shall be commenced for Material within
         a period of not more than thirty (30) days after delivery thereof.
         Company's failure to notify Supplier of a defect within such thirty
         (30) day period shall be deemed to constitute acceptance. The
         inspection and testing shall be in accordance with the quality control
         procedures and tests agreed upon by the Parties.

(c )     Facility Surveys. Company reserves the right to review, during
         regular business hours and following reasonable notice to Supplier,
         Supplier's physical facilities and Supplier's quality control
         procedures, both prior to first Material deliveries and periodically
         thereafter, in order to assure compliance with the Specifications and
         other standard industry practices and procedures. Supplier shall
         maintain quality control procedures mutually agreed upon by Company and
         Supplier as a result of such facility survey. In the event that Company
         determines in good faith, during any facilities survey, that Supplier's
         procedure is insufficient to insure consistent acceptable quality,
         Company shall so advise Supplier, specifying the deficiency Company
         believes exists and reasonable proposals for correction. In the event
         that Supplier shall fail to effect the suggested correction or
         reasonably satisfy Company as to the lack of need for such correction
         within thirty (30) days, Company may terminate this Agreement with
         regard to affected Materials and cancel all then-outstanding Purchase
         Orders for Materials without liability or consequence.

(d)      Acceptance Testing Results. Company shall provide notification to
         Supplier upon completion of acceptance testing setting forth the
         specific date of acceptance or rejection of Material included in the
         notification. If any Material is rejected, 



                                       11
<PAGE>

         Supplier shall thereafter proceed forthwith to correct the defects
         indicated by Company, either by repairing the defective Material at the
         point of delivery or within Supplier's facility, if possible, or by
         supplying a new Material. The cost associated with any such repair or
         replacement, including transportation charges for return to Supplier
         and subsequent return to Company, shall be borne by Supplier. The
         transportation costs will be borne by Company if it is determined that
         the Material was improperly rejected. Material for which acceptance
         tests are not completed within thirty (30) days after delivery to the
         FOB point shall be deemed to have been accepted by Company as of such
         time.

(e)      Failure to Meet Minimum Standards. If, during either qualification or
         acceptance testing, Company determines that the Materials are not
         defect-free or cannot comply with minimum quality standards or as
         otherwise established between the Parties, this Agreement may be
         terminated with respect to such Materials at Company's option and
         Company may cancel without liability or consequence any Purchase Order
         previously issued.

(f)      Supplier Personnel. Supplier shall provide, at Company's request and at
         locations selected by Company, and at no charge to Company, technically
         competent personnel of Supplier, chosen by Supplier, to assist in the
         identification and resolution of any performance problems which may
         jeopardize the progress of the first installation of Material. Supplier
         shall also provide, at Company's request, any performance information
         available from any source which could aid Company in evaluation of
         Material performance.

(g)      No Waiver of Warranty. In no event shall the inspection, qualification,
         and acceptance of any Material, or the payment for any such Material by
         Company, in any way impair or reduce Company's rights under Section 4.1
         of this Agreement, or Company's rights to further inspection or
         testing.


5.3      QUALITY -

         (A) Supplier commits to attaining and maintaining "acceptable " ratings
(or equivalent) on all quality system elements per a Quality System Audit (QSA)
as periodically performed by Company.

         (B) Supplier commits to ensure that all Supplier manufacturing and
design operations which contribute to the design, development, production, and
service of material are ISO 9001 and 9002 certified.

         (C) Supplier commits to establish an end of the line Quality Assurance
audit on Material by a date to be set forth in relevant Product Letters. The
focus of this audit shall be to replicate user application of Material as
specified by Company's customer. Test and examination of Material under the
quality audit shall be at a system level, and shall


                                       12
<PAGE>

include but is not limited to a system for continuous monitoring of all primary
and ancillary product functions and fault detection of the Material while under
this test.

         Supplier shall continuously review customer return data to ensure that
the scope of the product quality audit function includes the
requirement(s)/condition(s) under which the return failed. Supplier shall
perform a detailed failure mode analysis of all Material found defective through
the end of the line product quality audit in line with the requirements and
process outlined in paragraph E below.

         (D) Supplier commits to establishing a program of tracking return
rates. Material which has been in operation for any period of time up to, and
including, one full year shall be considered part of this tracking program. For
the purpose of this Article, the term "circuit pack" shall be used to define the
lowest replaceable unit of material supplied to Company.

         For the purpose of calculating the return rate, the population shall be
all circuit packs shipped during a quarter. The returns shall be those circuit
packs shipped during the quarter that are returned/received during the time
period beginning three (3) months after the end of the quarter being measured,
and ending after fifteen (15) months following said quarter.

         All returns will be included in the calculation of the return rate
including, but not limited to, failures, no trouble founds and recalls. The
return rate is to be calculated using the following equation:


10,000 x returns (from Qtr. pop.) during months 3-15 post target Qtr.
- ---------------------------------------------------------------------
                  Population of target Qtr.

This calculation shall be made for product manufactured during each fiscal
quarter of this Agreement.

         Supplier shall measure and report return rates on a quarterly basis to
Company and comply with the return rate requirement in accordance with the
following schedule:

Manufactured               Return Rate               Annual
Date                       Requirement               Measurement Due
- --------------------------------------------------------------------
Jan.- Dec.                ***********                April

         The Annual Measurement will be the summation of the number of returns
received during the defined time period of each quarter of the year divided by
the summation of the populations of each quarter times ten thousand.

         (E) Supplier commits to establishing a system for tracking and
analyzing all Material returned by Company to it, as well as any Material
failures which occur through Company's end of the line Quality Assurance audit.
For all Material in the above two 



                                       13
<PAGE>

categories, Supplier shall perform a failure mode analysis, which at a minimum
will be down to the component level. Component level failure modes will be
recorded and failed components found defective will be accumulated for the
purpose of determining repetitive occurrences.

         Material shall be considered defective if it fails to meet the warranty
Specifications under this Agreement (including performance and appearance
Specifications) or if during testing, installation or use, the Material fails to
operate as expected or specified.

         Supplier shall continuously monitor, and analyze, data on material
returned by Company to it, as well as Material found through the end of the line
Quality Assurance Audit, for the purpose of determining: (a) return rates in
excess of expectations as outlined in paragraph (D) of this Article; or (b)
repetitive occurrences of the same component level problem. Supplier shall
provide to Company on a quarterly basis, written summary reports of said
analysis.

         If Supplier determines instances where Material return rate is in
excess of the requirements as outlined in paragraph (D) , then Supplier shall
provide a written Corrective Action Report to Company, explaining in detail the
nature of the problem detected, and the step(s) Supplier proposes to correct the
problem. This completed report is to be provided to Company no later than thirty
(30) days following the occurrence or detection of the condition which required
the corrective action.

As part of the plan to correct the problem, it is agreed that Supplier shall:

         a)   Incorporate the remedy in affected material in accordance with the
              change control procedures set forth in Supplier's change control
              process.

         b)   Ship all subsequent material incorporating the required
              modification correcting the problem at no additional charge to
              Company; and

         c)   Repair and/or replace previously shipped material that may contain
              the same problem trend. In the event that Company incurs costs due
              to such repair and/or replacement, including but not limited to
              labor and shipping costs, Supplier shall reimburse Company for
              such reasonable costs. Supplier shall bear risk of in transit loss
              and damage for such repaired and/or replaced material.

         Supplier and Company shall mutually agree in writing as to the
implementation schedule of the corrective action plan. Supplier shall use its
best efforts to implement the plan in accordance with the agreed upon schedule.
Company shall be entitled to postpone, at no charge to Company, further
deliveries of orders until such time as the remedy is implemented consistent
with this Article.

                                       14
<PAGE>

         (F) If Supplier 1) fails to meet the customer return rate established
in paragraph (D) during any period of three months or more; or 2) fails to issue
Corrective Action Reports as required in paragraph (E); or 3) fails to implement
a correction action in a manner and time frame agreed to by Company, then
Company may, in addition to any other remedies it may have: 1) develop and
implement such remedy for already purchased Material, the reasonable cost of
which will be borne by Supplier; 2) cancel or postpone other orders without
liability and return all Material affected by the problem for full refund,
payable by Supplier within thirty (30) days after receipt of returned material
(with risk of loss or in transit damage borne by Supplier).

         (G) As part of a program of continuous improvement, Supplier shall
establish annually, improvement goals for a series of key quality objectives.
These goals should include, but are not limited to: a) customer return rates as
specified in paragraph (D), b) Quality Assurance product quality audit defect
rates, and c) final system test yields. Supplier shall track these goals on a
monthly basis and to commit the resources necessary for the attainment of these
goals.


5.4 REPAIRS NOT COVERED UNDER WARRANTY - In addition to repairs provided for in

reasonably competitive price for such Material at the time for delivery.
Further, if requested by Company, Supplier shall take the necessary steps to
dispose of the unrepairable Material and pay to Company the salvage value, if
any.

         Replacement and repaired Material shall be warranted as set forth in
Section 4.1.

         This Agreement does not grant Supplier an exclusive privilege to repair
any or all of the Material purchased under this Agreement for which Company may
require repair; and Company may perform the repairs or contract with others for
these services. In addition, Supplier authorizes Company and any qualified
repairer with whom Company may contract to perform repairs on all Material

arising out of this Agreement 

     (b) First:

          (i) either Party may give written notification of such dispute or
     disagreement to the other Party and

          (ii) the Parties shall communicate with each other promptly with a
     view to resolving such dispute or disagreement within 21 days (or such
     extended period as the Parties agree is appropriate in any case) after such
     written notification is given.

     (c) The giving of any notice regarding any dispute or disagreement under
this Section 10.1 shall toll the running of all applicable statutes of
limitation until the later of (i) 90 days following the giving of such notice or
(ii) 30 days following the termination of discussions between the Parties
concerning such dispute or disagreement.

     (d) Second, if at the end of the 21 day period referenced in Section

mediation. Following such request, the Parties shall endeavor in good faith

disagreement and in attempting to reach a mutually acceptable business
resolution. Such mediation process shall terminate not later than 30 days
following the request therefor (or such extended or shorter period as the
Parties agree is appropriate). All applicable statutes of limitation shall be
tolled during the period of mediation.

     (e) Third, if at the end of the 30 day period referenced in Section 10.1(d)
(as it may be extended or shortened) such dispute or disagreement has not been
resolved to the satisfaction of both parties, either Party (the "complainant")
may commence binding arbitration by giving the other Party (the "respondent")
notice in writing (the "initiating notice") setting forth in reasonable detail
the nature of its claim and the relief requested stating that the complainant is
invoking the procedures set forth in this Section 10.1(e) and (f) and naming the
complainant's representative on the Arbitration Panel (as defined below). Within
21 days of receipt of an initiating notice, the respondent shall give the
complainant notice in writing (the "response") setting forth in reasonable
detail: (1) the 



                                       22
<PAGE>


basis of its response to the claim; (2) the nature of any counterclaim it has
against the complainant arising from the same set of facts and circumstances
that gave rise to the original claim; (3) any other counterclaim that Party
wishes to bring at that time (although the Party has no obligation to bring such
counterclaims at that time); (4) the relief requested; and (5) naming the
respondent's representative on the Arbitration Panel. The two representatives
shall select a third person who is mutually acceptable to them. If the
representatives fail to make such selection within 21 days, the complainant and
the respondent shall each replace its representative with a new representative
and the new representatives shall be subject to the preceding sentence and this
sentence. Once a third person is selected, such person together with the
representatives of the complainant and the respondent shall form the Arbitration
Panel. The date upon which the Arbitration Panel is formed shall be the
"Commencement Date". 

     (f) The Arbitration Panel shall conduct proceedings to determine the merits
under applicable law of the claims set forth in the initiating notice and the
response. The proceedings shall be administered by JAMS/Endispute in accordance
with its Comprehensive Arbitration Rules and Procedures in effect as of the
Effective Date, subject to the following additional rules: 

          (i) the proceedings shall take place in New York City;

          (ii) the Arbitration Panel (including, if necessary, any
     replacement(s) to the Arbitration Panel) shall be selected as set forth in
     Section 10.1(e);

          (iii) the available relief shall include damages, injunctive relief
     and equitable relief to the extent allowed under the applicable law, this
     Agreement and any other agreement between the parties;

          (iv) the parties shall attempt in good faith promptly to agree on the
     nature and extent of any discovery in connection with the arbitration,
     provided that, in the absence of such agreement, discovery shall be
     governed by JAMS/Endispute's Comprehensive Arbitration Rules and
     Procedures. In addition, the applicable law with respect to privilege and
     other protections from disclosure, including the work product doctrine,
     shall apply;

          (v) the final decision of the Arbitration Panel (the "Award") shall be
     issued within six months of the Commencement Date (the date of issuance of
     the Award being the "Award Date") and must be joined by at least two
     members of the Arbitration Panel;

          (vi) each party to the proceedings shall pay its own costs in
     connection with the proceedings, including the costs and expenses of its
     representative on the Arbitration Panel, and the parties shall share
     equally the other costs of the proceedings, including the fees of the third
     member of the Arbitration Panel, except that the prevailing party shall be
     entitled to recover its attorneys' fees incurred in prosecution thereof.
     
     (g) In accordance with the Federal Arbitration Act, 9 U.S.C. ss.1 et seq.,
the Award shall be final and binding and judgment thereon may be entered by any
state or federal court having jurisdiction thereof.

     (h) Nothing in this Section 10.1 shall be construed to preclude either
party from seeking injunctive relief in a court of competent jurisdiction to
prevent imminent irreparable harm. The dispute resolution procedures set forth
herein shall be stayed 


                                       23

available for Company's review upon request.

     For such changes or modifications which DO have an impact on performance,
reliability, Form, Fit, or Function, Supplier shall identify each such change or
modification in accordance with the classifications contained in the above Bell
Communications Research document via a Product Change Notification (PCN) form.
The Company shall immediately acknowledge receipt of the PCN to the
address/contact as stated on the PCN form and shall have thirty (30) calendar
days to advise Supplier if the proposed change or modification is unacceptable.
If Company notifies Supplier as required herein, that the proposed change or
modification is unacceptable, Supplier shall not implement such change or
modification. Company may reject any MATERIAL offered by Supplier which has been
changed or modified in a manner unacceptable to Company.

     If Company has not notified Supplier that the change or modification is
unacceptable within thirty (30) calendar days following issuance of the Change
Notification, Supplier shall implement the change or modification as described
in the Change Notification.

     If during the review of a proposed PCN, which has a classification of
either A or AC, issued by Supplier during the Warranty period of the affected
MATERIAL, the Company determines that implementation of the PRODUCT CHANGE will
cause the Company to incur "unreasonable expenses" such as, but not limited to,
expenses resulting from escorting Supplier's personnel to numerous Company
locations containing affected MATERIAL or repeated product changes to the same
item of MATERIAL within a one (1) year time period, the Company shall so notify
Supplier, in writing, prior to the implementation of such PRODUCT CHANGE.



                                       32
<PAGE>


     Upon such notification, the Company and Supplier shall jointly determine
the implementation procedure which will utilize the Supplier's and/or Company's
personnel in the most cost effective manner.

     If Supplier and the Company conclude the agreed to implementation procedure
will probably cause the Company to incur "unreasonable expenses", the Company
and Supplier shall jointly determine the likely extent of such expenses and
agree, in writing, to a "not to exceed" estimate for such expenses. In no event
shall such estimate exceed the Company's purchase price for the MATERIAL to be
changed. The Company shall track and record all such expenses associated with
the PRODUCT CHANGE. Upon completion of its efforts, the Company shall submit to
Supplier, for reimbursement by Supplier, an invoice of the Company's
"unreasonable expenses" within forty-five (45) calendar days after the Company's
receipt of such invoice.

     Issuing a Class A or AC product Change Notification shall not constitute an
agreement to provide such a change, but shall be construed as a recommendation
by the Supplier that the change is absolutely necessary.

2.6      FORECASTS - Company shall provide Supplier with six (6) month
rolling forecasts of Material it believes it will purchase from Supplier.
However, said forecasts are only provided to assist Supplier in planning its
manufacturing activities and they do not commit or bind Company to purchase or
the Supplier to supply any Materials, or any quantity of Materials. A forecast
only becomes binding upon the Parties when a Purchase Order, as set forth below,
is forwarded by Company to Supplier and Supplier duly accepts it and the agreed
upon delivery schedule for each Purchase Order is within ninety (90) days,
except that such 90-day forecast commitment period may be altered by mutual
agreement of the Parties for particular Material described in the Product
Letters. At such time, any changes to the volume of Materials committed to by
the Parties shall be governed by Sections 2.7, 2.8 and 2.9 below.

2.7      PURCHASE ORDERS - Purchase Orders issued under this Agreement shall
be sent to the Lucent address specified on firm price quotes from Lucent to BBT
This Agreement shall incorporate the typed or written provisions on Company's
orders issued pursuant to this Agreement. Printed provisions on Company's orders
(except as specified otherwise in this Agreement), boilerplate provisions in
electronic orders and all provisions on Supplier's forms shall be deemed
deleted. Estimates or forecasts furnished by Company shall not constitute
commitments, except as otherwise set forth in this Agreement.

         Purchase Orders shall specify: (a) description of Material, inclusive
of any numerical/alphabetical identification referenced in the price list in
this Agreement, (b) delivery date, (c) applicable price, (d) location to which
the Material is to be shipped and (e) location to which invoices shall be sent
for payment.

         Orders consistent with the Company forecast and requesting delivery
more than ninety (90) days (or the alternate forecast commitment period
specified for particular Material in the applicable Product Letter) from the
date the order is received by Supplier will be accepted or rejected by Supplier
in writing within five (5) business days of receipt of the order. Orders
requesting delivery in less than ninety days or which exceed the forecast shall
be deemed accepted unless Supplier provides written notice to the contrary
within ten (10) business days from receipt of the order.

         Company may at any time subsequent to the issuance of a Purchase Order
under this Agreement change the Purchase Order quantity at no charge in
accordance with the schedule below:

                                       4

<PAGE>


         Number of Days Prior to    Allowable Increase/Decrease
         Scheduled Shipment Date            (% of P.O. Quantity)

         0-90 (or 0-alternate forecast       0%          0%
         commitment period)


         91-greater (or alternate
         forecast commitment
         period-greater)                    100%   100%

Company will make reasonable efforts to provide forecasts and purchase orders
for Material that avoid sharp increases or decreases in production.

2.8      SHIPPING - Supplier shall: (1) ship the Material covered by this
Agreement or order complete unless instructed otherwise; (2) ship to the
destination designated in the Agreement or order; (3) ship according to routing
instructions given by Company; (4) refer to this Agreement and the order number
on all subordinate documents; (5) enclose a packing memorandum with each
shipment and, when more than one package is shipped, identify the package
containing the memorandum; and (6) mark the Agreement and order number on all
packages and shipping papers. Adequate protective packing shall be furnished at
no additional charge. Shipping and routing instructions may be furnished or
altered by Company without a writing. All deliveries will be FOB Supplier's
factory. If Supplier does not comply with Company's written shipping or routing
instructions, Supplier authorizes Company to deduct from any invoice of Supplier
(or to charge back to Supplier), any increased costs incurred by Company as a
result of Supplier's noncompliance.

2.9      SHIPPING INTERVAL - The delivery schedule applicable to each
Purchase Order will be set forth in the Purchase Order.

         If Supplier does not deliver by the delivery date specified in the
applicable Purchase Order, then in addition to all other rights and remedies at
law or equity or otherwise, and without any liability or obligation of Company,
Company shall have the right to: (a) cancel such Purchase Order following the
expiration of a five (5) business day grace period, or (b) extend such delivery
date to a later date, subject, however, to the right to cancel as in (a)
preceding if delivery is not made or performance is not completed on or before
such extended delivery date. If Company elects to extend such delivery date,
Supplier shall absorb the difference between the charges to ship normal
transportation and the charges to ship premium overnight.

         If a Purchase Order is canceled by Company pursuant to the above,
Company shall have the right to retain or return any or all material received by
or paid for by Company under such purchase order. Within fifteen (15) days of
Supplier's receipt of returned material, Supplier shall reimburse Company for
the reasonable costs of shipping



                                       5

the material returned to Supplier and for any amounts, including shipping costs,
previously paid by Company for the Material. Company shall pay for any Material
it retains at the prices set forth in the applicable Product Letters, less
applicable discounts which shall be applied on the basis of the quantity
specified in the Purchase Order.

         If, during the course of this Agreement, Supplier determines that
Supplier will no longer be able to ship within the above interval, Supplier
shall immediately notify Company's buyer to that effect. Supplier shall also
notify Company's buyer, as soon as it becomes apparent, if Supplier is unable to
meet the delivery date for an order. However, nothing contained in this
paragraph shall waive Company's rights as set forth above in this Section.

2.10     TITLE AND RISK OF LOSS - Title and risk of loss and damage to
Material purchased by Company under this Agreement shall vest in Company when
the Material has been delivered at the FOB point. If this Agreement or an order
issued pursuant to this Agreement calls for additional services to be performed
after delivery, Supplier shall retain title and risk of loss and damage to the
Material until the additional services have been performed. If Supplier is
authorized to invoice Company for Material upon shipment or prior to the
performance of additional services, title to Material shall vest in Company upon
payment of the invoice, but risk of loss and damage shall pass to Company when
the additional services have been performed.

2.11     TITLE TO MATERIAL FURNISHED BY COMPANY - In the event that Company
provides components to Supplier for use in Material ("Components"), or provides
Supplier with capital equipment, such as a test facility ("Capital Goods"),
Supplier acknowledges and agrees that Company has and shall have at all times
all right, title and interest in Components or Capital Goods furnished directly
or indirectly to Supplier by Company under this Agreement. Supplier shall,
within ten (10) days of receipt of the Components or Capital Goods, notify
Company in writing of any claims for quantity variation or quality problems in
the Components or Capital Goods furnished to Supplier. Supplier assumes
responsibility for any loss or damage to such Components or Capital Goods and
shall be liable for the full and actual value of the Components or Capital
Goods. Supplier shall store the Components or Capital Goods safely, indoors in
protected areas approved by Company at Supplier's facility. If Supplier removes
all or any part of the Components or Capital Goods from one building to another,
Supplier shall continue to be responsible for loss and damage and Supplier shall
give Company at least ten (10) business days advance notice, in writing, of the
removal except when the removal is required during Supplier's manufacturing
process or to protect the Components or Capital Goods from damage or loss.

         Company may inspect, inventory and authenticate the account of the
Components or Capital Goods during Supplier's normal business hours. Supplier
shall provide Company access to the premises wherein all such Components or
Capital Goods are located. The Components or Capital Goods shall be kept
segregated in an area marked "PROPERTY OF BROADBAND TECHNOLOGIES." For purposes
of this Section, the 

                                        6
<PAGE>

term " BroadBand Technologies " shall be deemed to mean BroadBand Technologies
Inc. or the BroadBand Technologies Inc. affiliated or associated company which
owns the Components or Capital Goods, as applicable.

         Supplier shall use the Components or Capital Goods only in the
manufacture of Material furnished to Company or otherwise in performing under
this Agreement.

         Supplier shall not allow any security interest, lien, tax lien or other
encumbrance (collectively referred to as "Encumbrance") to be placed on any
Components or Capital Goods. Supplier shall give Company immediate written
notice should any third party attempt to place or place an Encumbrance on such
Components or Capital Goods. Supplier shall indemnify and hold Company harmless
from any such Encumbrance. Supplier shall, at Company's request, promptly
execute a "protective notice" UCC-1 form and all other documents reasonably
necessary to enable Company to protect its interest in such Components or
Capital Goods. The Parties agree that this Agreement shall constitute the
security agreement required by the UCC of the appropriate state.

         The obligations assumed by Supplier with respect to the Components or
Capital Goods are for the protection of Company's property. If Supplier defaults
in carrying out Supplier's obligations under this Agreement, then, at no cost to
Company and upon five (5) working days notice to Supplier, Company may cancel
this Agreement with regard to affected Materials or withdraw all or any part of
the Components or Capital Goods, or both. Supplier shall, at Company's option,
return to Company or hold for Company's disposition any and all of such
Components or Capital Goods (including any scrap produced as a by-product) in
Supplier's possession at (a) the completion of the order, (b) expiration,
cancellation or termination of this Agreement, or (c ) the withdrawal of
Components or Capital Goods, as provided above.

                                   3. SERVICES

3.1      SERVICES - Visits by Supplier's representatives or its suppliers'
representatives for inspection, adjustment or other similar purposes in
connection with Material purchased under this Agreement shall for all purposes
be deemed "Work under this Agreement" and shall be at no charge to Company
unless otherwise agreed in writing between the Parties.

3.2      TECHNICAL SUPPORT AND TRAINING - At the time a purchase order is
entered into by the Parties, they shall determine, negotiating in good faith,
the level and extent of technical support appropriate for the Material ordered.
However, the Parties hereby agree that the Company shall be entitled to a
mutually agreed upon level of ongoing technical support, which shall include
field service and assistance, and they further agree that the availability or
performance of this technical support service shall not be construed as altering
or affecting Supplier's obligations as set forth in Section 4.1 or elsewhere
provided for in this Agreement. Further, Supplier shall provide instructors and
the necessary instructional material to provide a mutually agreed upon level of

                                       7

training sufficient to train Company's instructors in the installation, planning
and practices, operation, maintenance and repair of the Material.

                     4. WARRANTY AND LIMITATION OF LIABILITY

4.1      WARRANTY - Supplier warrants to Company and Company's customers, as
defined in this Section, that hardware, including firmware, furnished will be
new, free from defects in design, material and workmanship and will conform to
and perform in accordance with the Specifications for a period of ***********
after delivery, and that software furnished will conform to and perform in all
material respects with the Specifications for a period of ************** after
delivery; provided however, that if significant software defects are discovered,
equating to Severity Levels 1 or 2, Company may require a software fix from
Supplier for up to ***************** from delivery.

         If Material furnished contains one or more manufacturer's warranties
that are assignable, Supplier hereby assigns such warranties to Company and
Customers. Supplier warrants that at the time of delivery to Company such
Material shall be free of any security interest or any other lien or any other
encumbrance whatsoever. All warranties shall survive inspection, acceptance and
payment. Different warranty periods may be specified in the applicable Product
Letters.

         Defective or non-conforming Material will, at Supplier's option, either
be returned to Supplier for repair or replacement, at no cost to Company, with
risk of in-transit loss and damage borne by Supplier and freight paid by
Supplier, or be repaired or replaced by Supplier on Company's or Company's
customers' site or another site designated by Company at no cost to Company.
Unless otherwise agreed upon by Supplier and Company, Supplier shall complete
repairs and ship the repaired Material within ten (10) working days of receipt
of defective or non- conforming Material, or at Company's option, ship
replacement Material within ten (10) working days after verbal notification is
given Supplier by Company.

         If Material returned to Supplier or made available to Supplier on site
for repair as provided for in this Section is determined to be beyond repair,
Supplier shall promptly so notify Company and, unless otherwise agreed to in
writing by Supplier and Company, ship replacement Material without charge within
ten (10) days of such notification.

         Replacement Material shall be warranted as set forth above in Section
4.1. Any Material which is repaired, modified, or otherwise serviced by Supplier
shall be warranted as provided in this Section 4.1 for the remainder of the
warranty period (based upon the date repair, modification or other service is
completed and accepted by Company) or ninety (90) days after the Material is
returned to a customer of Company, whichever is later.

EXCEPT AS SET FORTH ABOVE, SUPPLIER DISCLAIMS ALL WARRANTIES, EXPRESS AND
IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED


                                        8
<PAGE>

WARRANTIES OF MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR PURPOSE.

4.2      LIMITATION OF LIABILITY - NEITHER PARTY SHALL BE LIABLE FOR ANY
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR FOR LOSS OF PROFITS, REVENUE
OR DATA, WHETHER IN AN ACTION IN CONTRACT, TORT, STRICT LIABILITY, OR OTHERWISE,
EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

                                   5. QUALITY

5.1      EPIDEMIC CONDITION - If, during the term of this Agreement and for
five years after the last shipment date of Material under this Agreement,
Company notifies Supplier that Material shows evidence of an "Epidemic
Condition," Supplier shall prepare and propose a Corrective Action Plan ("CAP")
with respect to such Material within ten (10) working days of such notification,
addressing implementation and procedure milestones for remedying such Epidemic
Condition(s). An extension of this time-frame is permissible upon mutual written
agreement of the Parties.

         Upon notification of the Epidemic Condition to Supplier, Company shall
have the right to postpone all or part of the shipments of unshipped Material
exhibiting the Epidemic Condition, by giving written notice of such postponement
to Supplier, pending correction of the Epidemic Condition. Such postponement
shall temporarily relieve Supplier of its shipment liability and Company of its
shipment acceptance liability. Should Supplier not agree to the existence of an
Epidemic Condition or should Company not agree to the CAP, then Company shall
have the right to suspend all or part of its unshipped orders without liability
to Company until such time as a mutually acceptable solution is reached.

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

  (1)    Failure reports or statistical samplings show that four (4) percent or
         more of Material installed or four (4) percent or more of Material
         shipped during any two consecutive months, or four (4) percent or more
         of the Material tracked by Company's Field Quality Engineering contain
         a potential safety hazard (such as personal injury or death, fire,
         explosion, toxic emissions, etc.), or exhibit a highly objectionable
         symptom (such as emissions of smoke, loud noises, deformation of
         housing) or other disconcerting symptoms of this type.

(2)      Reliability plots of relevant data indicate that the Material has
         actual Mean Time Between Failures (MTBF) of less than 80% of the MTBF
         stipulated in the Technical Specification. The MTBF parameter of
         Material is defined as the total operating or power-on time of any
         population under observation ("T"), in hours, divided by the total
         number of critical failures ("n") that have occurred during the

 
                                      9

<PAGE>

         observed period. A critical failure is defined as a failure to operate
         per the requirements of the Technical Specification. The total
         operating time of a population is the summation of operating time of
         individual units in that population. MTBF is expressed as MTBF = T/n.
         An Epidemic Condition shall exist when data derived from populations
         being tracked confirms the condition with 80% confidence.

(3)      Material Dead on Arrival (DOA) failures exceed the Epidemic DOA
failure rate which is defined as 1.2 x DOA rate specified in the applicable
Product Letter.

         Only major functional and visual/mechanical/appearance defects are
considered for determining Epidemic Condition. Material can be either sampled
or, at Company's option, 100% audited at Company warehouses, factories or
Company's customers' locations. If Material is sampled, the data must have 80%
or better statistical confidence.

         For the purpose of this Agreement, functional DOA shall be defined as
any Material that during the test, installation or upon its first use fails to
operate as expected or specified. Visual/mechanical/appearance DOA is defined as
any Material containing one or more major defects that would make the Material
unfit for use or installation.

         An Epidemic Condition shall not include failures due to customer
misapplication, utilization of parts not approved by Supplier, or chain failures
induced by internally or externally integrated subassemblies.

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

(a)      Incorporate the remedy in the affected Material in accordance with
         Company's Engineering Change Control procedures as set forth in
         Attachment 2;

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

(c)      Repair and/or replace Material that caused the Epidemic Condition. In
         the event that Company incurs costs due to such repair and/or
         replacement, including but not limited to labor and shipping costs,
         Supplier shall reimburse Company for such reasonable costs. Supplier
         shall bear risk of in transit loss and damage for such repaired and/or

<PAGE>

         If Supplier is unable to develop a mutually agreeable remedy, or does
not adequately take into account the business interests of Company, as
reasonably agreed by the Parties, Company may (1) develop and implement such
remedy and, in such case, reasonable implementation costs and risk of in-transit
loss and damage shall be allocated between the Parties as set forth in this
Section, and/or (2) cancel postponed orders without liability and return all
Material affected by such Epidemic Condition for full refund, payable by
Supplier within thirty (30) days after receipt of returned Material (with risk
of loss or in-transit damage borne by Supplier).

5.2      INSPECTION, ACCEPTANCE TESTING, AND QUALITY CONTROL STANDARDS

(a) Ongoing Inspection and Testing. All Material shall be subject, at either
Supplier's manufacturing facility or at Company premises, to further inspection,
acceptance testing, and review for conformance to ongoing quality control
standards as may be established in the Specifications.

(b) Acceptance Inspection and Acceptance Testing. All Material shall be subject
to acceptance inspection and testing by Company, at Company's election, on
Supplier's premises, during normal business hours and following a reasonable
notice to Supplier, on Company's premises, or at a location selected by Company
(including the premises of any customer of Company). When conducted on
Supplier's premises by Supplier, copies of all documents prepared by Supplier
indicating the results of such inspection and testing shall be provided to
Company at Company's request. Inspection and testing at Company's facilities or
locations designated by Company shall be commenced for Material within a period
of not more than thirty (30) days after delivery thereof. Company's failure to
notify Supplier of a defect within such thirty-day period shall be deemed to
constitute acceptance. The inspection and testing shall be in accordance with
the quality control procedures and tests agreed upon by the Parties.

(c ) Facility Surveys. Company reserves the right to review, during regular
business hours and following reasonable notice to Supplier, Supplier's physical
facilities and Supplier's quality control procedures, both prior to first
Material deliveries and periodically thereafter, in order to assure compliance
with the Specifications and other standard industry practices and procedures.
Supplier shall maintain quality control procedures mutually agreed upon by
Company and Supplier as a result of such facility survey. In the event that
Company determines in good faith, during any facilities survey, that Supplier's
procedure is insufficient to insure consistent acceptable quality, Company shall
so advise Supplier, specifying the deficiency Company believes exists and
reasonable proposals for correction. In the event that Supplier shall fail to
effect the suggested correction or reasonably satisfy Company as to the lack of
need for such correction within thirty (30) days, Company may terminate this
Agreement with regard to affected Materials and cancel all then-outstanding
Purchase Orders for Materials without liability or consequence.

                                       11

<PAGE>

(d) Acceptance Testing Results. Company shall provide notification to Supplier
upon completion of acceptance testing setting forth the specific date of
acceptance or rejection of Material included in the notification. If any
Material is rejected, Supplier shall thereafter proceed forthwith to correct the
defects indicated by Company, either by repairing the defective Material at the
point of delivery or within Supplier's facility, if possible, or by supplying a
new Material. The cost associated with any such repair or replacement, including
transportation charges for return to Supplier and subsequent return to Company,
shall be borne by Supplier. The transportation costs will be borne by Company if
it is determined that the Material was improperly rejected. Material for which
acceptance tests are not completed within thirty (30) days after delivery to the
FOB point shall be deemed to have been accepted by Company as of such time.

(e) Failure to Meet Minimum Standards. If, during either qualification or
acceptance testing, Company determines that the Materials are not defect-free or
cannot comply with minimum quality standards or as otherwise established between
the Parties, this Agreement may be terminated with respect to such Materials at
Company's option and Company may cancel without liability or consequence any
Purchase Order previously issued.

(f) Supplier Personnel. Supplier shall provide, at Company's request and at
locations selected by Company, and at no charge to Company, technically
competent personnel of Supplier, chosen by Supplier, to assist in the
identification and resolution of any performance problems which may jeopardize
the progress of the first installation of Material. Supplier shall also provide,
at Company's request, any performance information available from any source
which could aid Company in evaluation of Material performance.

(g) No Waiver of Warranty. In no event shall the inspection, qualification, and
acceptance of any Material, or the payment for any such Material by Company, in
any way impair or reduce Company's rights under Section 4.1 of this Agreement,
or Company's rights to further inspection or testing.

5.3      QUALITY -

         (A) Supplier commits to attaining and maintaining "acceptable " ratings
(or equivalent) on all quality system elements per a Quality System Audit (QSA)
as periodically performed by Company.

         (B) Supplier commits to ensure that all Supplier manufacturing and
design operations which contribute to the design, development, production, and
service of material are ISO 9001 and 9002.

         (C) Supplier commits to establish an end of the line Quality Assurance
audit on Material by a date set forth in the relevant Product Letters. The focus
of this audit shall be to replicate user application of Material as specified by
Company's customer. Test and examination of material under the quality audit
shall be at a system level, and shall


                                       12
<PAGE>

include but is not limited to a system for continuous monitoring of all primary
and ancillary product functions and fault detection of the Material while under
this test.

         Supplier shall continuously review customer return data to ensure that
the scope of the product quality audit function includes the
requirement(s)/condition(s) under which the return failed. Supplier shall
perform a detailed failure mode analysis of all Material found defective through
the end of the line product quality audit in line with the requirements and
process outlined in paragraph E below.

         (D) Supplier commits to establishing a program of tracking return
rates. Material which has been in operation for any period of time up to, and
including, one full year shall be considered part of this tracking program. For
the purpose of this Article, the term "circuit pack" shall be used to define the
lowest replaceable unit of Material supplied to Company.

         For the purpose of calculating the return rate, the population shall be
all circuit packs shipped during a quarter. The returns shall be those circuit
packs shipped during the quarter that are returned/received during the time
period beginning three (3) months after the end of the quarter being measured,
and ending after fifteen (15) months following said quarter.

         All returns will be included in the calculation of the return rate
including, but not limited to, failures, no trouble founds and recalls. The
return rate is to be calculated using the following equation:

10,000 x returns (from Qtr. pop.) during months 3-15 post target Qtr.
- ---------------------------------------------------------------------
                  Population of target Qtr.

This calculation shall be made for product manufactured during each fiscal
quarter of this Agreement.

         Supplier shall measure and report return rates on a quarterly basis to
Company, and comply with the return rate requirement in accordance with the
following schedule:

Manufactured               Return Rate               Annual
Date                         Requirement    Measurement Due
- -----------------------------------------------------------
Jan.-Dec.                     *********              April

The Annual Measurement will be the summation of the number of returns received
during the defined time period of each quarter of the year divided by the
summation of the populations of each quarter times ten thousand.

         (E) Supplier commits to establishing a system for tracking and
analyzing all Material returned by Company to it, as well as any Material
failures which occur through Company's end of the line Quality Assurance audit.
For all Material in the above two 



                                       13
<PAGE>

categories, Supplier shall perform a failure mode analysis, which at a minimum
will be down to the component level. Component level failure modes will be
recorded and failed components found defective will be accumulated for the
purpose of determining repetitive occurrences.

         Material shall be considered defective if it fails to meet the warranty
Specifications under this Agreement (including performance and appearance
Specifications) or if during testing, installation or use, the material fails to
operate as expected or specified.

         Supplier shall continuously monitor, and analyze, data on material
returned by Company to it, as well as Material found through the end of the line
Quality Assurance Audit, for the purpose of determining: (a) return rates in
excess of expectations as outlined in paragraph (D) of this Article; or (b)
repetitive occurrences of the same component level problem. Supplier shall
provide to Company on a quarterly basis, written summary reports of said
analysis.

         If Supplier determines instances where Material return rate is in
excess of the requirements as outlined in paragraph (D) , then Supplier shall
provide a written Corrective Action Report to Company, explaining in detail the
nature of the problem detected, and the step(s) Supplier proposes to correct the
problem. This completed report is to be provided to Company no later than thirty
(30) days following the occurrence or detection of the condition which required
the corrective action.

         As part of the plan to correct the problem, it is agreed that Supplier
shall:

         a) Incorporate the remedy in affected Material in accordance with the
         change control procedures set forth in Supplier's change control
         process.

         b) Ship all subsequent Material incorporating the required modification
         correcting the problem at no additional charge to Company; and

         c) Repair and/or replace previously shipped Material that may contain
         the same problem trend. In the event that Company incurs costs due to
         such repair and/or replacement, including but not limited to labor and
         shipping costs, Supplier shall reimburse Company for such reasonable
         costs. Supplier shall bear risk of in transit loss and damage for such
         repaired and/or replaced material.

         Supplier and Company shall mutually agree in writing as to the
implementation schedule of the Corrective Action Plan. Supplier shall use its
best efforts to implement the plan in accordance with the agreed upon schedule.
Company shall be entitled to postpone, at no charge to Company, further
deliveries of orders until such time as the remedy is implemented consistent
with this Article.



                                       14
<PAGE>

         (F) If Supplier 1) fails to meet the customer return rate established
in paragraph (D) during any period of three months or more; or 2) fails to issue
Corrective Action Reports as required in paragraph (E); or 3) fails to implement
a correction action in a manner and time frame agreed to by Company, then
Company may, in addition to any other remedies it may have: 1) develop and
implement such remedy for already purchased Material, the reasonable cost of
which will be borne by Supplier; 2) cancel or postpone other orders without
liability and return all material affected by the problem for full refund,
payable by Supplier within thirty (30) days after receipt of returned Material
(with risk of loss or in transit damage borne by Supplier).

         (G) As part of a program of continuous improvement, Supplier shall
establish annually, improvement goals for a series of key quality objectives.
These goals should include, but are not limited to: a) customer return rates as
specified in paragraph (D), b) Quality Assurance product quality audit defect
rates, and c) final system test yields. Supplier shall track these goals on a
monthly basis and to commit the resources necessary for the attainment of these
goals.

5.4      REPAIRS NOT COVERED UNDER WARRANTY - In addition to repairs

If requested by Company, Supplier will sell to Company a replacement at the
price set forth in Supplier's then current agreement with Company for said
Material or, if no such agreement exists, at a price agreed upon by Supplier and
Company. If the Parties fail to agree on a price, the price shall be a
reasonably competitive price for such Material at the time for delivery.
Further, if requested by Company, Supplier shall take the necessary steps to
dispose of the unrepairable Material and pay to Company the salvage value, if
any.

         Replacement and repaired Material shall be warranted as set forth in
Section 4.1.

         This Agreement does not grant Supplier an exclusive privilege to repair
any or all of the Material purchased under this Agreement for which Company may
require repair; and Company may perform the repairs or contract with others for
these services. In addition, Supplier authorizes Company and any qualified
repairer with whom Company may contract to perform repairs on all Material
purchased under this Agreement.

         All transportation costs and in transit risk of loss and damage to
Material returned to Supplier for repair under this Section will be borne by
Company and all transportation



                                       15

                                  10. DISPUTES

10.1      DISPUTE RESOLUTION -
(a) The following procedures shall apply to any dispute or disagreement between
the Parties or any of their Related Parties arising out of this Agreement.
         (b)  First:
                  (i) either Party may give written notification of such dispute
         or disagreement to the other Party and
                  (ii) the Parties shall communicate with each other promptly
         with a view to resolving such dispute or disagreement within 21 days
         (or such extended period as the Parties agree is appropriate in any
         case) after such written notification is given. 

         (c) The giving of any notice regarding any dispute or disagreement
under this Section 10.1 shall toll the running of all applicable statutes of
limitation until the later of (i) 90 days following the giving of such notice or
(ii) 30 days following the termination of discussions between the Parties
concerning such dispute or disagreement.
         
         (d) Second, if at the end of the 21 day period referenced in Section
10.1(b) (as it may be extended) such dispute or disagreement has not been
resolved to the satisfaction of both parties, either Party may request in
writing that such dispute or disagreement be the subject of non-binding
mediation. Following such request, the Parties shall endeavor in good faith
promptly to identify a single person (who shall be a person with experience and
good reputation) who shall assist the Parties in discussing such dispute or
disagreement and in attempting to reach a mutually acceptable business
resolution. Such mediation process shall terminate not later than 30 days
following the request therefor (or such extended or shorter period as the
Parties agree is appropriate). All applicable statutes of limitation shall be
tolled during the period of mediation.

         (e) Third, if at the end of the 30 day period referenced in Section
10.1(d) (as it may be extended or shortened) such dispute or disagreement has
not been resolved to the satisfaction of both parties, either Party (the
"complainant") may commence binding arbitration by giving the other Party (the
"respondent") notice in writing (the "initiating notice") setting forth in
reasonable detail the nature of its claim and the relief requested stating that
the complainant is invoking the procedures set forth in this Section 10.1(e) and
(f) and naming the complainant's representative on the Arbitration Panel (as
defined below). Within 21 days of receipt of an initiating notice, the
respondent shall give the complainant notice in writing (the "response") setting
forth in reasonable detail: (1) the basis of its response to the claim; (2) the
nature of any counterclaim it has against the complainant arising from the same
set of facts and circumstances that gave rise to the original claim; (3) any
other counterclaim that Party wishes to bring at that time (although the Party
has no obligation to bring such counterclaims at that time); (4) the relief
requested; and (5) naming the respondent's representative on the Arbitration
Panel. The two representatives shall select a third person who is mutually
acceptable to them. If the representatives fail to make such selection within 21
days, the complainant and the respondent shall each replace its representative
with a new representative and the 

                                       22
<PAGE>

new representatives shall be subject to the preceding sentence and this
sentence. Once a third person is selected, such person together with the
representatives of the complainant and the respondent shall form the Arbitration
Panel. The date upon which the Arbitration Panel is formed shall be the
"Commencement Date".

         (f) The Arbitration Panel shall conduct proceedings to determine the
merits under applicable law of the claims set forth in the initiating notice and
the response. The proceedings shall be administered by JAMS/Endispute in
accordance with its Comprehensive Arbitration Rules and Procedures in effect as
of the Effective Date, subject to the following additional rules:
                  (i) the proceedings shall take place in New York City; 
                  
                   (ii) the Arbitration Panel (including, if necessary, any
         replacement(s) to the Arbitration Panel) shall be selected as set forth
         in Section 10.1(e); 

                   (iii) the available relief shall include damages, injunctive
         relief and equitable relief to the extent allowed under the applicable
         law, this Agreement and any other agreement between the parties; 

                   (iv) the parties shall attempt in good faith promptly to
         agree on the nature and extent of any discovery in connection with the
         arbitration, provided that, in the absence of such agreement, discovery
         shall be governed by JAMS/Endispute's Comprehensive Arbitration Rules
         and Procedures. In addition, the applicable law with respect to
         privilege and other protections from disclosure, including the work
         product doctrine, shall apply; 

                   (v) the final decision of the Arbitration Panel (the "Award")
         shall be issued within six months of the Commencement Date (the date of
         issuance of the Award being the "Award Date") and must be joined by at
         least two members of the Arbitration Panel; 

                   (vi) each party to the proceedings shall pay its own costs in
         connection with the proceedings, including the costs and expenses of
         its representative on the Arbitration Panel, and the parties shall
         share equally the other costs of the proceedings, including the fees of
         the third member of the Arbitration Panel, except that the prevailing
         party shall be entitled to recover its attorneys' fees incurred in
         prosecution thereof. 

                   (g) In accordance with the Federal Arbitration Act, 9 U.S.C.
         ss.1 ET SEQ., the Award shall be final and binding and judgment thereon
         may be entered by any state or federal court having jurisdiction
         thereof.

                   (h) Nothing in this Section 10.1 shall be construed to
         preclude either party from seeking injunctive relief in a court of
         competent jurisdiction to prevent imminent irreparable harm. The
         dispute resolution procedures set forth herein shall be stayed pending
         disposition of any application for such relief. The Parties agree that
         a court of competent jurisdiction may consider the merits of any claim
         that is subject to the dispute resolution procedures set forth herein
         to the extent necessary to resolve any permissible application for
         injunctive relief.

                                11. MISCELLANEOUS

                  "Product Changes" shall be administered in accordance with
         Bell Communications Research document GR 209 CORE, Issue 2, January
         1996, titled "Generic Requirements for Product Change Notices," which
         is incorporated herein by reference.

                  Supplier may make changes to MATERIAL, modify drawings, or
         make changes to manufacturing specifications, provided the changes,
         modifications, or substitutions DO NOT have an impact on the
         performance, reliability, Form, Fit, or Function of the MATERIAL
         without prior notification to Company. Supplier shall maintain written
         records of all such changes, and make these records available for
         Company's review upon request.

                  For such changes or modifications which DO have an impact on
         performance, reliability, Form, Fit, or Function, Supplier shall
         identify each such change or modification in accordance with the
         classifications contained in the above Bell Communications Research
         document via a Product Change Notification (PCN) form. The Company
         shall immediately acknowledge receipt of the PCN to the address/contact
         as stated on the PCN form and shall have thirty (30) calendar days to
         advise Supplier if the proposed change or modification is unacceptable.
         If Company notifies Supplier as required herein, that the proposed
         change or modification is unacceptable, Supplier shall not implement
         such change or modification. Company may reject any MATERIAL offered by
         Supplier which has been changed or modified in a manner unacceptable to
         Company.

                  If Company has not notified Supplier that the change or
         modification is unacceptable within thirty (30) calendar days following
         issuance of the Change Notification, Supplier shall implement the
         change or modification as described in the Change Notification.

                  If during the review of a proposed PCN, which has a
         classification of either A or AC, issued by Supplier during the
         Warranty period of the affected MATERIAL, the Company determines that
         implementation of the PRODUCT CHANGE will cause the Company to incur
         "unreasonable expenses" such as, but not limited to, expenses resulting
         from escorting Supplier's personnel to numerous Company locations
         containing affected MATERIAL or repeated product changes to the same
         item of MATERIAL within a one (1) year time period, the Company shall
         so notify Supplier, in writing, prior to the implementation of such
         PRODUCT CHANGE.

                                       33
<PAGE>


                  Upon such notification, the Company and Supplier shall jointly
         determine the implementation procedure which will utilize the
         Supplier's and/or Company's personnel in the most cost effective
         manner.

                  If Supplier and the Company conclude the agreed to
         implementation procedure will probably cause the Company to incur
         "unreasonable expenses", the Company and Supplier shall jointly
         determine the likely extent of such expenses and agree, in writing, to
         a "not to exceed" estimate for such expenses. In no event shall such
         estimate exceed the Company's purchase price for the MATERIAL to be
         changed. The Company shall track and record all such expenses
         associated with the PRODUCT CHANGE. Upon completion of its efforts, the
         Company shall submit to Supplier, for reimbursement by Supplier, an
         invoice of the Company's "unreasonable expenses" within forty-five (45)
         calendar days after the Company's receipt of such invoice.

                  Issuing a Class A or AC product Change Notification shall not
         constitute an agreement to provide such a change, but shall be
         construed as a recommendation by the Supplier that the change is
         absolutely necessary.

associated  fees payable by Lucent to BBT for such  Projects,  which the Parties
shall  consider under this Agreement for  performance  under a suitable  Project
Letter.  The Parties recognize that the list of potential  Projects on such list

executed  by both  Parties.  Except  as  agreed by BBT,  the  Projects  that are
selected   by  the   Parties   shall   all   relate   to  the   development   of

            Parties to administer the various Projects shall be:

      (i)   Monitoring   all  Project   activities,   including   processing  of

      (b) The  individuals  shall not discuss  marketing  or pricing of products
sold by Lucent or BBT.

2.04 BBT shall deliver to Lucent the  Deliverables set forth in executed Project

Project Letters for approximately ********************************* within sixty
(60) days from the Effective Date; at least ******************************* more
by October 1, 1998; and the remaining ******************************* in Project
Letter  work by  October 1, 1999.  In the event that the  Parties  are unable to
execute  the  Project  Letters  by that  date,  the  Parties  agree to  initiate
accelerated arbitration to resolve all disputes that may be preventing agreement
on the Project Letters, using a single arbitrator, no discovery, and a period of
arbitration  from  initiation  to completion  of  arbitration  of no longer than
thirty (30) days.

2.06 The  Parties  may at any time during  this  Agreement  agree to  additions,
deductions or deviations  (all  hereinafter  referred to as a "Change") from the
Deliverables.  No Change  shall be  considered  as an  addition,  alteration  or
deduction  from the  Deliverables,  nor shall BBT be entitled to any  additional
compensation for work done pursuant to or in  contemplation of a Change,  unless
made pursuant to a written  instruction  from Lucent ("Change  Order") issued by
Lucent.  BBT shall not be required to accept any Change,  but agrees to consider
all Change  Orders in good  faith.  In no event  shall any Change  decrease  the
aggregate  amount  specified in Section  3.01(a) to be paid by Lucent under this
Agreement.  Increases  in the price to be paid by Lucent for any Change shall be
consistent with the method of pricing of the original Deliverables.

2.07 (a) Lucent shall evaluate each  Deliverable  furnished under this Agreement
for compliance with the  Specifications and shall submit a written acceptance or
rejection  to BBT within the period for  acceptance/rejection  specified  in the
relevant Project Letter after the receipt by Lucent of the complete Deliverable.
Except as provided in this Section 2.07, Lucent may exercise its right to reject
any  Deliverables  or  portions  thereof  only on account of the  failure of the
Deliverables to meet the  Specifications.  Acceptance or rejection shall be made
only in writing by the Lucent Representative provided,  however, that failure to
reject   any   Deliverables   or   portions   thereof   within  the  period  for
acceptance/rejection  specified in the relevant  Project Letter shall constitute
acceptance. In no event shall early turnover of the Deliverable by BBT to Lucent
or use  during  the  evaluation  period  of such  Deliverable  by  Lucent or its
customers  for  business,  profit,  revenue or any other  lawful use  constitute
acceptance of such Deliverable by Lucent.  Lucent shall have the right to accept
or reject portions of any Deliverable. Any rejection of a Deliverable or portion
thereof  shall  identify  the failure to meeting  Specifications  in  reasonable
detail sufficient to allow BBT to correct the deficiency.

(b) If a  Deliverable  evaluated  pursuant to Section  2.07(a) is rejected,  BBT
agrees to correct,  at its expense,  the failure to meet the  Specifications for
the Deliverable  (referred to herein  collectively as "defect")  leading to such
rejection  and resubmit the  corrected  Deliverable  to Lucent within sixty (60)
days after receipt of notice from Lucent of such defect or such longer period as
is consistent  with industry  practice for the identified  defect  (collectively
referred to herein as the  "Corrective  Period").  Lucent shall have thirty (30)
days (or such longer period as is consistent  with industry  practice) after the
resubmitting of such corrected Deliverable to accept or reject such Deliverable.
If the  corrected  deliverable  complies  with  the  Specifications,  BBT  shall
incorporate the corrections in the Deliverable.

(c) If the  defects  in a  rejected  Deliverable  are not  corrected  within the
Corrective Period or if a resubmitted  Deliverable  re-tested or re-evaluated by
Lucent during the sixty (60) day  re-evaluation  period is again rejected,  then
Lucent may at its option: (1) retain the Deliverable at an equitable  adjustment
in price as may be agreed by the parties,  in which case that deliverable  shall
be deemed  accepted;  (2) afford  BBT one or more  correction  extensions  for a
period or periods to be specified by Lucent. Unless otherwise



                                       7
<PAGE>


agreed,  during such  optional  extension by Lucent,  Lucent may  terminate  the
Project for Deliverable that has been rejected. BBT shall refund that portion of
the  price of the  Project  previously  paid to BBT  which is in  excess  of its
equitable adjustment referred to above if the defects are not corrected prior to
termination by Lucent. Lucent may not terminate this Agreement.

(d) Lucent shall have no obligation  to accept any  Deliverable  delivered  more
than six months after the delivery date  specified for such  Deliverable  in the
relevant Project Letter.

2.08 Work on any  Deliverable  shall not be performed  outside the United States
without the consent of the Lucent, which shall not unreasonably be withheld.

2.09 (a) It is  expressly  understood  and agreed that this  Agreement  does not
grant to BBT an exclusive  right or privilege to develop for Lucent  products of
the type described in this Agreement which Lucent may require. It is, therefore,
understood that Lucent may, and fully intends to, contract with other developers
for the procurement of comparable development.  In addition, Lucent shall at its
sole  discretion,  decide the extent to which  Lucent  will  market,  advertise,
promote,  support, or otherwise assist in further offerings of the products. BBT
understands  and  agrees  that  Lucent  intends to and will have  alternate  and
supplemental  sources  for the  development  work  set  out in  this  Agreement.
Notwithstanding  the  foregoing,  it is further  understood  and agreed  that if
Lucent utilizes non-BBT sources for the same or similar  development  work, then
such shall not relieve Lucent of its commitments hereunder to pay BBT twenty-one
million dollars ($21,000,000).

      (b) BBT agrees that this  Agreement  shall  neither  restrict the right of
Lucent to cease  purchasing the  Deliverables nor require Lucent to continue any
level of such purchases  after payment by Lucent of twenty-one  million  dollars
($21,000,000) (subject to Section 6.02) pursuant to this Agreement.

2.10 If BBT or Lucent has  knowledge  that  anything  prevents or  threatens  to
prevent the timely delivery of any Deliverable  under this Agreement,  including
delays in  transfer  by Lucent of  information  BBT  requires  to  perform  this
Agreement,  BBT or  Lucent  as the case may be,  shall  immediately  notify  the
Representative  of  the  other  party  and  include  all  relevant   information
concerning the delay or potential delay.

2.11 If requested by Lucent,  BBT will, without additional charge to Lucent: (a)
provide instructors and the necessary  instructional  material of BBT's standard
format to train Lucent's personnel in the installation,  planning and practices,

Agreement,  with these  classes  to be  conducted  at  reasonable  intervals  at

                                     PAYMENT

3.01 (a) Lucent and BBT agree that the Parties shall execute Project Letters for
Projects  and  Deliverables  having an  aggregate  value of  twenty-one  million
dollars ($21,000,000.00). This sum shall exclude capital expenditures to be made
pursuant to any Project  Letters,  which shall be at Lucent's  expense,  and all
capital equipment  purchased through such expenditures shall be owned by Lucent.
On the first day of each calendar quarter for the 12 calendar quarters after the
earlier to occur  ofApril 1, 1998 or  execution  and delivery by both Parties of
the one or more  Project  Letters  having a price of at least the  amount of the
first installment,  Lucent will pay BBT One Million Seven Hundred Fifty Thousand
Dollars  ($1,750,000),  unless the Parties  mutually agree upon an adjustment to
that amount in view of the  anticipated  volume of activity  during the calendar
quarter  following  the  adjusted  quarter.  However,  if  mutually  agreed upon
milestones  have not been met by BBT  through  no  fault of  Lucent  during  any
previous  quarter,  then the  advance  payment  for  upcoming  quarters  will be
reasonably  adjusted  accordingly.  BBT shall provide to Lucent,  on a quarterly
basis,  an  accounting  report  which  compares  the dollar  amount of completed
Deliverables to amounts paid by Lucent pursuant to the scheduled payments.  Upon
the earlier of the  termination  of this  Agreement  or  completion  of the last
Project,  the Parties shall make such payments to one another as shall cause the
aggregate amount paid by Lucent to equal the amount agreed to be paid under this
Section, subject to adjustment as provided in Sections 2.06, 2.07, and 6.02.

(b) The  Parties  will  attempt  in good  faith to select  projects  related  to
****************************************  which are useful to both Parties. Each
Project Letter shall include a "Reusability Value". Such Reusability Value shall
be the mutually agreed value of the Project Deliverables to BBT.****************
********************************************************************************
********************************************************************************
********************************************************************************
***********************************  and such aggregate  Reusability  Value.  If
this  Agreement is terminated  prior to the third  anniversary  of the Effective
Date, the ******* *********************** amount shall be reduced pro rata based
on the  percentage  of the three (3) year period after the  Effective  Date that
occurred  prior to the date of termination  and Lucent shall pay to BBT,  within
ninety (90) days of termination,  an amount equal to the difference  between the
pro rata reduced amount and the aggregate Reusability Value.

charges  whatsoever.  Lucent  reserves the right to require proof that all third
parties furnishing labor and materials for the Deliverables have been paid.

3.03 Lucent shall reimburse BBT only for the following tax payments with respect
to transactions under this Agreement unless Lucent advises BBT that an exemption
applies:  state and local sales and use taxes,  as applicable.  Taxes payable by
Lucent  shall be billed as  separate  items on BBT's  invoices  and shall not be
included in BBT's  prices.  Lucent  shall have the right to have BBT contest any
such taxes that Lucent deems  improperly  levied at Lucent's expense and subject
to Lucent's direction and control.

hereof;

      c) license  under any claim of any patent which BBT has a right to license
as of the effective date of this Agreement  which would be infringed by a Lucent

appropriate.

      (b) BBT  warrants  to Lucent  that the final  design for each  Deliverable
provided  by BBT to Lucent  under this  Agreement  will be free of defects  that
would cause the  Deliverable  produced  according to that design to fail to meet
the Specifications for that Deliverable agreed by the parties. In addition,  BBT
warrants to Lucent that final software for each  Deliverable  provided by BBT to
Lucent  under this  Agreement  shall  conform with the  Deliverable  performance
Specifications  agreed by the Parties,  and to BBT's  knowledge  will be free of
Severity 1 and Severity 2 Defects.  These  warranties,  for the final design and
software provided under this Agreement for each Deliverable,  shall continue for
a period of ********  after the final design and  software for that  Deliverable
are  accepted by Lucent,  or for such longer  period  specified  in the relevant
Project Letter.

      (c) With regard to Installed Prototypes, if Installed Prototypes furnished
contain one or more assignable manufacturer's warranties, BBT shall be deemed to
have assigned such warranties to Lucent and customers at delivery.  BBT warrants
that at the time of



                                       13

delivery to Lucent,  Installed Prototypes shall be free of any security interest
or any other lien or any other  encumbrance  whatsoever.  All  warranties  shall
survive inspection, acceptance and payment.

      (d)  Defective  or  non-conforming  Installed  Prototypes  will,  at BBT's
option,  either be  returned  to BBT for  repair or  replacement,  at no cost to
Lucent, with risk of in-transit loss and damage borne by BBT and freight paid by
BBT, or be repaired or replaced by BBT on Lucent's or Lucent's  customers'  site
or another  site  designated  by Lucent at no cost to  Lucent.  If the defect is
related to defective workmanship of materials or manufacture, BBT shall complete
repairs and ship the repaired  material  within ten (10) working days of receipt
of defective or non-conforming material, or at Lucent's option, ship replacement
material within ten (10) working days after verbal  notification is given to BBT
by Lucent.  If the defect is related to design or  software,  the  parties  will
agree on a schedule for correction.

      (e) BBT's sole liability,  and Lucent's  exclusive  remedy,  for claims by
Lucent for  defective  or  non-conforming  materials  made  during the  relevant
warranty period, shall be: (1) for designs or software, at no additional cost to
Lucent,  correction  of the  design  or  software  to  make it  conforming,  and
providing a copy of the  corrected  design or  software  to Lucent;  and (2) for
Installed Prototypes,  at no additional cost to Lucent, correcting the defective
Installed Prototypes as provided in this clause.

      (f)  Replacement  material  shall be  warranted as set forth above in this
section.  Any  Installed  Prototype  which is repaired,  modified,  or otherwise
serviced by BBT shall be warranted as provided in this section for the remainder
of the warranty  period  (based upon the date of repair,  modification  or other
service is  completed  and  accepted  by  Lucent) or ninety  (90) days after the
Installed Prototype is returned by BBT, whichever is later.

5.02 (a) BBT  believes  the BBT  Information  and  Developed  Information  to be
furnished  hereunder  will be true and accurate.  Except as provided in Sections
2.07 and  5.01,  BBT and its  Subsidiaries  shall not be  liable  for  errors or
omissions in the BBT Information or the Developed Information.

      (b) BBT  warrants  that the BBT  Information  licensed  to Lucent  and the
Developed  Information  to be furnished to Lucent under this  Agreement  are and
will be the  original  work of BBT (or BBT has and  will  have a valid  right to
license  such  property)  and it has the power to grant the rights  described in
this Agreement. BBT warrants and represents that upon Lucent's acceptance of the
Deliverables,  such  Deliverables  shall be free of any security interest or any
other lien or any other encumbrance whatsoever.

dates  falling on or after January 1, 2000, in the same manner and with the same
functionality  as it performed  before January 1, 2000. This maintenance will be
considered part of and



                                       14
<PAGE>


covered  under the  maintenance  provisions  of the  Agreement at no  additional
charge to Lucent.

5.04  EXCEPT  AS  PROVIDED  IN THIS  ARTICLE,  BBT MAKES NO  REPRESENTATIONS  OR
WARRANTIES, EXPRESS OR IMPLIED. BY WAY OF EXAMPLE BUT NOT OF LIMITATION, BBT AND
ITS SUBSIDIARIES MAKE NO  REPRESENTATIONS  OR WARRANTIES OF  MERCHANTABILITY  OR
FITNESS FOR ANY PARTICULAR  PURPOSE,  OR THAT THE USE OF THE BBT  INFORMATION OR
THE DEVELOPED  INFORMATION  OR ANY PORTION OF IT WILL NOT INFRINGE ANY PATENT OF
ANY THIRD PARTY, AND IT SHALL BE THE SOLE  RESPONSIBILITY OF LUCENT TO MAKE SUCH
DETERMINATION  AS IS NECESSARY WITH RESPECT TO THE ACQUISITION OF LICENSES UNDER
PATENTS  OF THIRD  PARTIES.  BBT AND ITS  SUBSIDIARIES  SHALL NOT BE HELD TO ANY
LIABILITY  WITH RESPECT TO ANY PATENT  INFRINGEMENT  CLAIM MADE BY LUCENT OR ANY
THIRD PARTY ON ACCOUNT OF, OR ARISING  FROM THE USE OF, THE BBT  INFORMATION  OR
DEVELOPED INFORMATION OR ANY PORTION OF IT.

5.05 At Lucent's  request,  BBT agrees to  indemnify,  defend and hold  harmless
Lucent,  its  affiliates,  customers,  employees,  successors  and assigns  (all
referred to as "Lucent") from and against any losses,  damages,  claims,  fines,
penalties and expenses (including  reasonable attorney's fees) that arise out of
or result from: (1) assertions under Workers'  Compensation or similar acts made
by persons  furnished  by BBT; and (2) injuries or death to persons or damage to
property,  including  theft,  in any way  arising out of or caused or alleged to
have been caused by the  Deliverable  or  activities  performed  by, or material
provided by BBT or persons furnished by BBT: (a) if the Deliverables do not meet
the  specifications,  except to the  extent  such  injury or death to persons or
damage to property is caused by the  negligence or willful or other wrongful act
or omission of Lucent or its  employees;  and (b) if the  Deliverables  meet the
Specifications,  to the  extent  such  injury or death to  persons  or damage to
property  is  caused by the  negligence  or  willful  or other  wrongful  act or
omission of BBT or its employees.

5.06  Neither  Lucent  nor BBT shall be liable  for any loss,  damage,  delay or
failure of performance  resulting directly or indirectly from any cause which is
beyond  its  reasonable  control,  including  but  not  limited  to acts of God,
extraordinary  traffic conditions,  riots, civil  disturbances,  wars, states of
belligerency or acts of the public enemy, strikes, work stoppages,  or the laws,
regulations,  acts or failure to act of any governmental authority. In the event
that  performance  under this Agreement is prevented for a continuous  period of
two (2) months or longer by any of the  foregoing  causes,  the Party which does
not  receive the  benefit of the  performance  of the other Party shall have the
right to terminate this Agreement by giving written notice to the other Party.

unless Lucent notifies BBT of its intention to exercise that right within thirty
(30) days (or such  longer  period as may be agreed to) of  Lucent's  receipt of
notice from BBT of a planned or actual Change in Control. A Change of Control of
BBT which results from  bankruptcy  proceedings  shall be treated as a Change of
Control of BBT. In the event that this  Agreement is terminated as a result of a
rejection  of this  Agreement by a Trustee in  bankruptcy,  Lucent shall have no

      the Project Letter; or

      (2) Make no further  payments  under the Project  Letter to BBT  following
      termination of the  Agreement,  in which case BBT shall be released of its
      obligations  under the Project  Letter.  BBT shall be entitled to keep any
      payments made under the Project  Letter prior to  termination,  and Lucent
      shall be entitled to receive BBT's development work in process relative to
      Deliverables  specified  in  the  Project  Letter  (including  prototypes,
      drawings,  and the  like).  For  purposes  of  clarification  the  Parties

      Information and a joint right to receive copies of the development work in
      process.

Lucent shall have no obligation to make any payments  under Section 3.01 not due
prior to the date of termination.

(c) Except in the case of Section  6.02(a)(1),  BBT's license under Section 4.03
shall be terminated,  upon which  termination  BBT shall  immediately  return to

is filed by or against BBT, unless BBT provides to Lucent reasonable  assurances
that BBT will be able to  comply  with the  confidentiality  provisions  of this
Agreement  regarding  intellectual  property,  Lucent may  terminate the license
granted in Section  4.03  hereof.  BBT shall  immediately  notify  Lucent of the
filing  of any  bankruptcy  petition  by or  against  BBT.  Notwithstanding  the
foregoing,  a Change in Control of BBT which  results from  bankruptcy  proceeds
shall be treated as provided in Section 6.01.

(b) If a  proceeding  is  commenced  under any  provision  of the United  States
Bankruptcy Code, voluntary or involuntary,  by or against either party, and this
Agreement has not been terminated,  the non-debtor party may file a request with
the  bankruptcy  court to have the court set a date within sixty (60) days after
the  commencement  of the case,  by which the debtor party will assume or reject
this Agreement, and the debtor party shall cooperate and take whatever steps are
necessary to assume or reject the Agreement by such date.

6.04 In the event Lucent  terminates  any license  right of BBT  hereunder,  any
obligation of BBT to Lucent which requires use of such terminated license, shall
immediately  terminate.  The rights of the Parties  shall be governed by Section

materials or other inventory to be transferred,  provision of reports, files and
similar media necessary for continuation of the work  transferred,  continuation
of work at  reducing  levels if  necessary  during a  transition  period  and at
reduced levels if work is transferred in part.  Prices for additional  work such
as packing and preparation for shipment,  and revision of prices  resulting from
revised volumes, if necessary, shall be mutually agreed upon by the Parties.

            any of the Lucent  Information or the BBT  Information,  as the case
            may be, than are necessary for its use hereunder;

      (iv)  that  it  will  not,  without  the  other  party's  express  written
            permission,  (a) use in  advertising,  publicity,  or otherwise  any
            trade name,  trademark,  trade device,  service mark,  symbol or any
            other identification or any abbreviation,  contraction or simulation
            thereof   owned  or  used  by  such  other   party  or  any  of  its
            Subsidiaries,  or (b) represent,  directly or  indirectly,  that any
            product or service  produced in whole or in part with the use of any
            of the Lucent  Information or the BBT  Information,  as the case may
            be,  is a  product  or  service  of such  other  party or any of its
            Subsidiaries   or  is  made  in  accordance  with  or  utilizes  any
            information  or  documentation  of  the  other  party  or any of its
            Subsidiaries;  provided,  however, that nothing in this Section 7.01
            shall be construed as prohibiting a party from  representing that it
            is licensed with respect to such information; and

      (v)   that the Lucent Information or the BBT Information,  as the case may
            be, and all documents furnished hereunder are deemed to be and shall
            remain  the  property  of  the  furnishing   party,  and  that  upon
            termination of this  Agreement,  each shall upon request  deliver to
            the  other  party  all  documents   containing  any  of  the  Lucent
            Information  or the BBT  Information,  as the case  may be,  and all
            copies  thereof  then under such party's or its  supplier's  control
            (except to the extent  such party is  entitled  hereunder  to retain
            such information).

7.02 It is  recognized  that  during the  performance  of this  Agreement,  each
Party's  personnel  may  unavoidably  receive  or  have  access  to  private  or
confidential  information of the other Party which is not the BBT Information or
the Lucent  Information.  Each



                                       18
<PAGE>


Party agrees that all such information  shall be treated for the purposes of the
provisions  of  this  Agreement  as  if  it  were  BBT   Information  or  Lucent
Information, as the case may be.

7.03 (a) A party receiving proprietary or confidential information in connection
with this Agreement,  including the Lucent  Information and the BBT Information,
will (i)  maintain  it in  confidence  and will not  disclose  any part of it to
anyone except those of its employees,  agents or advisors  having a need to know
in order to accomplish the purposes of this Agreement and who are bound by terms
similar to those of this  section,  (ii) use at least the same degree of care to
maintain  its  secrecy  as it  uses  in  maintaining  the  secrecy  of  its  own
confidential and trade secret information of equal importance,  (iii) always use
at least a reasonable degree of care in maintaining its secrecy, and (iv) use it
only for the purpose of exercising  its rights and  performing  its  obligations
under this Agreement.

      (b) Neither party will have any obligation (confidentiality or restriction
on use) concerning that part of the other's information which (i) at the time of
disclosure  in  writing  is  not  marked  with  a  legend   identifying   it  as
"Proprietary",  "Confidential"  or a similar  legend or, within thirty (30) days
after oral  disclosure,  is not so  identified  in writing,  (ii) at the time of
disclosure to the receiving party was known to that party free of restriction as
evidenced  by  documentation  in that  party's  possession,  (iii)  is  lawfully
obtained from a third party under no obligation of  confidentiality,  (iv) is or
becomes publicly available other than as a result of an act or failure to act of
the receiving party, or (v) is independently developed by a party without use of
the other's confidential information.

(c)  If any  part  of a  party's  confidential  or  proprietary  information  is
wrongfully disclosed or used, then, in addition to the remedies provided by this
Agreement or by law or in equity,  the party which provides the information will
be entitled to an injunction preventing further disclosure of the information by
the other party or further  disclosure  or use of the  information  by any third
parties to whom the information has been wrongfully disseminated.

property.  BBT shall, at Lucent's option,  return to Lucent or hold for Lucent's
disposition  any or all of such Lucent  property in BBT's  possession at (a) the

of the Lucent Property , as provided above.

8.04 This Agreement and all transactions  under it shall be governed by the laws
of the State of New Jersey, without regard to conflicts of laws provisions.  The
Parties  agree to submit to the  jurisdiction  of any court wherein an action is
commenced  against  the  other  Party  based on a claim  for which one Party has
agreed to indemnify the other Party under this Agreement.

8.05 BBT and all persons furnished by BBT shall comply at their own expense with
all  applicable  laws,   ordinances,   regulations  and  codes,   including  the
identification  and  procurement of required  permits,  certificates,  licenses,

8.06 This Agreement shall  constitute the entire  agreement  between the parties
with respect to the subject  matter of this  Agreement and shall not be modified
or  rescinded,  except  by a  writing  signed by BBT and  Lucent.  Estimates  or
forecasts furnished by Lucent shall not constitute  commitments.  The provisions
of this  Agreement  supersede  all  contemporaneous  and prior oral and  written
communications  and  understandings  of the parties  with respect to the subject
matter of this Agreement.

8.07  Neither  Party  shall  implead or bring an action  against the other Party
based on any claim by any person for personal  injury or death to an employee of
a Party for which the



                                       20
<PAGE>


other Party has  previously  paid or is obligated  to pay worker's  compensation
benefits to such  employee or claimant  and for which such  employee or claimant
could not otherwise bring legal action against the other Party.

8.08 All persons  furnished by any Party shall be considered solely employees or
agents of that Party, who shall be responsible for payment of all  unemployment,
social security and other payroll taxes,  including  contributions when required
by law.

8.09 The obligations of the Parties under this Agreement,  which by their nature
would  continue  beyond the  termination,  cancellation  or  expiration  of this
Agreement,  shall  survive  termination,  cancellation  or  expiration  of  this
Agreement.

8.10 BBT shall maintain and cause BBT's  subcontractors  to maintain  during the
term of this Agreement: (1) Workers' Compensation insurance as prescribed by the
law of the  state or  nation  in which  the work is  performed;  (2)  employer's

liability  insurance shall designate Lucent  Technologies  Inc., its affiliates,
and its  directors,  officers  and  employees  (all  referred to as "Lucent") as
additional insured.  All such insurance must be primary and non-contributory and
required  to  respond  and pay prior to any other  insurance  or  self-insurance
available.  Any other  coverage  available  to Lucent  shall  apply on an excess
basis.  BBT agrees that BBT, BBT's  insurer(s) and anyone  claiming by, through,
under or in BBT's  behalf  shall  have no  claim,  right of  action  or right of
subrogation  against  Lucent and its  customers  based on any loss or  liability
insured against under the foregoing  insurance.  BBT shall furnish Lucent copies
of  certificates  of insurance upon request by Lucent.  In the event BBT changes
insurers, BBT shall notify Lucent of such change.  Insurance companies providing
coverage  under  this  Agreement  must be rated by A-M Best  with at least an A-

8.11 Each Party shall be responsible  for its own labor relations with any labor
organization either representing or seeking to represent its employees and shall
negotiate  and seek to adjust all disputes  between it and its  employees or any
union  representing its employees.  Except as otherwise provided in this clause,
and subject to the terms of this



                                       21
<PAGE>


Agreement,  either  Party may  freely  enter  into any  contract  with any union
representing  employees employed by it to perform the duties contemplated by the
requirements of this  Agreement.  Neither Party shall enter into a contract that
purports  to  obligate  the other  Party to the union,  either as  successor  or
assignee  of  such  Party,  or in any  other  way,  on the  termination  of this
Agreement,  or at any other time.  Each Party warrants that it is not a party to
any existing union contract purporting so to obligate the other Party.

8.12 Any notice or demand  which under the terms of this  Agreement or under any
statute  must or may be given or made by BBT or Lucent  shall be in writing  and

8.13  If  any  of  the  provisions  of  this  Agreement   shall  be  invalid  or
unenforceable,  such  invalidity  or  unenforceability  shall not  invalidate or
render  unenforceable  this entire  Agreement,  but rather this entire Agreement
shall be construed as if not containing the particular  invalid or unenforceable
provision or provisions,  and the rights and obligations of the parties shall be
construed and enforced accordingly.




                                       22
<PAGE>


8.14 The  failure  of either  Party at any time to  enforce  any right or remedy
available to it under this  Agreement or otherwise with respect to any breach or
failure by the other Party shall not be  construed  to be a waiver of such right
or remedy with respect to any other breach or failure by the other Party.

8.15 (a) The  following  procedures  shall apply to any dispute or  disagreement
between the Parties or any of their Subsidiaries arising out of this Agreement.

(b)  First:

            (i) either  Party may give written  notification  of such dispute or
      disagreement to the other Party and

            (ii) the Parties shall  communicate  with each other promptly with a
      view to  resolving  such dispute or  disagreement  within 21 days (or such
      extended  period as the Parties  agree is  appropriate  in any case) after
      such written notification is given.

(c) The giving of any notice  regarding any dispute or  disagreement  under this
Section  8.15 shall toll the running of all  applicable  statutes of  limitation
until the later of (i) 90 days  following  the giving of such  notice or (ii) 30
days following the  termination of  discussions  between the Parties  concerning
such dispute or disagreement.

(d) Second, if at the end of the 21 day period referenced in Section  8.15(b)(as
it may be extended)  such dispute or  disagreement  has not been resolved to the
satisfaction  of both  parties,  either  Party may request in writing  that such
dispute or disagreement be the subject of non-binding mediation.  Following such
request,  the Parties shall endeavor in good faith promptly to identify a single
person (who shall be a person with  experience  and good  reputation)  who shall
assist the Parties in discussing such dispute or disagreement  and in attempting
to reach a mutually acceptable business resolution. Such mediation process shall
terminate  not  later  than 30 days  following  the  request  therefor  (or such
extended or shorter period as the Parties agree is appropriate).  All applicable
statutes of limitation shall be tolled during the period of mediation.

(e) Third, if at the end of the 30 day period  referenced in Section 8.15(d) (as
it may be extended  or  shortened)  such  dispute or  disagreement  has not been
resolved to the satisfaction of both parties,  either Party (the  "complainant")
may commence  binding  arbitration by giving the other Party (the  "respondent")
notice in writing (the "initiating  notice") setting forth in reasonable  detail
the nature of its claim and the relief requested stating that the complainant is
invoking the procedures set forth in this Section 8.15(e) and (f) and naming the
complainant's representative on the Arbitration Panel (as defined below). Within
21 days of  receipt  of an  initiating  notice,  the  respondent  shall give the
complainant  notice in writing  (the  "response")  setting  forth in  reasonable
detail:  (1) the  basis of its  response  to the  claim;  (2) the  nature of any
counterclaim it has against the  complainant  arising from the same set of facts
and  circumstances  that  gave  rise  to  the  original  claim;  (3)  any  other
counterclaim  that Party wishes to bring at that time (although



                                       23
<PAGE>


the Party has no obligation to bring such  counterclaims  at that time); (4) the
relief  requested;  and  (5)  naming  the  respondent's  representative  on  the
Arbitration  Panel. The two  representatives  shall select a third person who is
mutually acceptable to them. If the representatives  fail to make such selection
within 21 days,  the  complainant  and the  respondent  shall each  replace  its
representative  with a new representative and the new  representatives  shall be
subject to the  preceding  sentence  and this  sentence.  Once a third person is
selected,  such person together with the  representatives of the complainant and
the  respondent  shall  form the  Arbitration  Panel.  The date  upon  which the
Arbitration Panel is formed shall be the "Commencement Date".

(f) The  Arbitration  Panel shall  conduct  proceedings  to determine the merits
under  applicable law of the claims set forth in the  initiating  notice and the
response.  The proceedings shall be administered by JAMS/Endispute in accordance
with its  Comprehensive  Arbitration  Rules and  Procedures  in effect as of the
Effective Date, subject to the following additional rules:

      (i)   the proceedings shall take place in New York City;

      (ii)  the Arbitration Panel (including,  if necessary,  any replacement(s)
            to the Arbitration  Panel) shall be selected as set forth in Section
            8.15(e);

      (iii) the available  relief shall include damages,  injunctive  relief and
            equitable  relief to the extent  allowed under the  applicable  law,
            this Agreement and any other agreement between the parties;

      (iv)  the  parties  shall  attempt in good faith  promptly to agree on the
            nature  and  extent  of  any  discovery  in   connection   with  the
            arbitration,  provided  that,  in the  absence  of  such  agreement,
            discovery  shall  be  governed  by  JAMS/Endispute's   Comprehensive
            Arbitration Rules and Procedures and the applicable law with respect
            to privilege and other  protections from  disclosure,  including the
            work product doctrine;

      (v)   the final decision of the  Arbitration  Panel (the "Award") shall be
            issued  within  six  months  of the  Commencement  Date (the date of
            issuance of the Award being the "Award  Date") and must be joined by
            at least two members of the Arbitration Panel;

      (vi)  each party to the proceedings  shall pay its own costs in connection
            with the  proceedings,  including  the  costs  and  expenses  of its
            representative on the Arbitration Panel, and the parties shall share
            equally the other costs of the  proceedings,  including  the fees of
            the  third  member  of  the  Arbitration  Panel,   except  that  the
            prevailing  party shall be entitled to recover its  attorneys'  fees
            incurred in prosecution thereof.

(g) In accordance with the Federal  Arbitration Act, 9 U.S.C.  ss.1 et seq., the
Award shall



                                       24
<PAGE>


be final and binding and judgment thereon may be entered by any state or federal
court having jurisdiction thereof.

(h) Nothing in this Section  8.15 shall be  construed  to preclude  either party
from seeking  injunctive relief in a court of competent  jurisdiction to prevent
imminent  irreparable harm. The dispute  resolution  procedures set forth herein
shall be stayed pending  disposition  of any  application  for such relief.  The
Parties agree that a court of competent  jurisdiction may consider the merits of
any claim that is subject to the dispute resolution  procedures set forth herein
to the extent  necessary to resolve any  permissible  application for injunctive
relief.

8.16 This Agreement may be executed in one or more counterparts.

8.17 Breach by a Party of any other  agreement  between  the  Parties  shall not
constitute a breach of this  Agreement,  unless the same  conduct  independently
breaches  this  Agreement.  A breach of this  Agreement  shall not  constitute a
breach of any other  agreement  between  the  Parties,  unless the same  conduct
independently breaches such other agreement.

     Re: Element Manager Software

Dear David:

     This will summarize our agreement respecting the potential use by BroadBand
Technologies, Inc. ("BBT") of Lucent Technologies' AnyMedia (TM) FAST Element
Manager Software platform ("EM Platform Software") as a basis for BBT's planned
development of application software for use with BBT's Digital Loop Carrier
("DLC") product ("EM Application Software").

Background

     In connection with the development and marketing of its DLC product, BBT
plans to develop EM Application Software. The EM Application Software will
require an element manager software platform of a type which is currently
available for license in the marketplace. Based on our discussions to date,
however, BBT is interested in the possibility of using the EM Platform Software
for that platform should it be: (1) compatible with BBT's planned architecture,
required features and required software development tool environment; (2)
attractively priced with acceptable commercial terms and conditions; and (3)
available in an acceptable time frame.

Lucent Architecture Decision

     As you know, the EM Platform Software is in the preliminary design stage at
this time and Lucent has not yet made some of the fundamental software
architecture decisions respecting the EM Platform Software which are an
understandable prerequisite to BBT's platform decision. Lucent will use
reasonable efforts to design this architecture in a manner which will
accommodate BBT's design criteria, as Lucent understands those criteria.
However, such a path may not be economically feasible and Lucent reserves the
right to advise BBT that it will not accommodate BBT's wishes. Lucent will
advise BBT in writing of that decision ("the Lucent Decision") as soon as
practicable but in no event more than sixty (60) days from the date of this
letter. Should Lucent decide not to attempt to accommodate BBT's criteria,
Lucent shall have no further obligations of any kind to BBT respecting the EM
Platform Software or the EM Application Software, except for the obligation to
pay BBT $2,000,000 as set forth below.

BBT Decision

                                        2

     Should the Lucent Decision be to design the EM Platform Software to
accommodate BBT's criteria, Lucent will provide BBT with information regarding:
(1) the details and direction of the EM Platform Software architecture and
intended development; (2) an anticipated availability date for the EM Platform
Software; and (3) a maximum royalty fee it would charge BBT for each copy of the
EM Platform Software sublicensed by BBT to a BBT customer in connection with the
EM Application Software. Lucent will provide this information to BBT as soon as
practicable but in no event more than ninety (90) days from the date of this
letter. BBT will decide within thirty (30) days from its receipt of the above
information whether or not to use the EM Platform Software as the basis for its
EM Application Software development and will advise Lucent in writing of that
decision. Should BBT decision be to use the EM Platform Software solution, BBT
and Lucent shall promptly negotiate a License Agreement which will establish
BBT's rights with respect to the EM Platform Software. It is Lucent's
understanding that, should BBT choose the EM Platform Software solution, BBT
intends to develop the EM Application Software in parallel with Lucent's
development of the EM Platform Software; BBT understands the risks inherent in
relying on a software product prior to the existence of final specifications.

Payment to BBT

     Within thirty (30) days of BBT's decision for or against using the EM
Platform Software or of a Lucent Decision not to accommodate BBT's design
criteria, whichever occurs first, Lucent will remit to BBT the sum of two
million dollars ($2,000,000) for BBT's use in connection with element manager
software.

Use of Information

     During the time period prior to the Lucent Decision or the BBT Decision, it
will be necessary for BBT and Lucent or one or more of Lucent's subsidiaries to
share with one another information of a proprietary nature. The parties agree to
safeguard each other's information in accordance with the following:

     All Information ("Information" means proprietary specifications, designs,
plans, drawings, software, data, prototypes or other business and /or technical
information) provided by either Party to the other shall be held in confidence
by the receiving Party, shall be used only in connection with the subject of
this letter agreement, shall be reproduced only to the extent necessary for that
purpose; and shall not be disclosed by the receiving Party without the prior
written approval of the disclosing Party. The receiving Party may, however,
disclose the Information to its employees, consultants and contractors with a
need to know; provided, that the receiving Party binds those employees,
consultants and contractors to terms at least as restrictive as those stated
herein, advises those employees, consultants and contractors of their
confidentiality obligations, and indemnifies the disclosing Party for any breach
of those obligations. Information shall be subject to the restrictions in this
section if it is in writing or other tangible form, only if clearly marked as
proprietary when disclosed to the receiving Party; or, if not in tangible form,
is of a nature that a reasonable person would conclude is confidential
Information, and the Information is reduced to writing clearly marked as

                                        3

proprietary, with a copy of the writing being furnished to the receiving Party
within thirty (30) days of the disclosure of the intangible information, and
with the writing containing a notice that the information was previously
provided in intangible form. These restrictions on the use or disclosure of
Information shall not apply to any Information: (i) which is independently
developed by or for the receiving Party; (ii) which is lawfully received free of
restriction from another source; (iii) after it has become generally available
to the public without breach of this Agreement by the receiving party; (iv)
which at the time of disclosure to the receiving Party was known to that Party
free of restriction as evidenced by documentation in that Party's possession;
(v) which the disclosing Party agrees in writing is free of such restrictions;
or (vi) which the receiving Party is required to disclose under applicable laws,
rules and regulations, provided that the receiving Party shall first notify the
disclosing Party of such required disclosure and afford the disclosing party the
opportunity to seek a protective order relating to such disclosure. All
Information shall remain the property of the disclosing Party and shall be
returned upon written request or upon the receiving Party's determination that
it no longer has a need for such Information. The receiving Party may retain one
copy of all written materials returned to provide an archive record of the
disclosure.

     Please indicate your agreement with the above by signing a copy of this
letter in the space indicated below.


                                                 Sincerely yours,

                                                 LUCENT TECHNOLOGIES INC.
