Agreement is a non-commitment contract and Materials and/or Services shall be
furnished by BBT on an "as-ordered" basis.

except as otherwise provided herein, continue in effect thereafter until

further liability pursuant to this Agreement or to any order which has been
assigned.

performed, or of any other interest hereunder, in whole or in part, shall be
void unless Bell Atlantic's written consent is obtained or the assignment is
confined solely to monies due or to become due. It is expressly agreed that any
such assignment of monies shall be void to the extent that it attempts to impose
upon Bell Atlantic obligations to the assignee additional to the payment of such
monies, or to preclude Bell Atlantic from dealing solely and directly with BBT

any time extends to any other customer lower prices or higher discounts for any
such material or services under similar terms and

                                       2


<PAGE>

prices or discounts to Bell Atlantic as of the date such prices or discounts
were first offered to the other customer. If, after the effective date of the
resulting price decrease, Bell Atlantic shall have overpaid for affected
Materials or Services at the pre-existing price, then the amount of the
overpayment shall, at Bell Atlantic's discretion, be allowed as a credit against
the price of Materials or Services on any order for which payment has not been
made or refunded to Bell Atlantic. In addition, such prices shall be at least as
low as those offered by Lucent to Bell Atlantic under agreement BC13760.

BUYER'S INFORMATION. All specifications, drawings, sketches, models, samples,
tools, computer programs, technical information, confidential business
information or data, written, oral or otherwise (all hereinafter designated
"Information") obtained from Bell Atlantic by BBT hereunder or in contemplation
hereof shall remain Bell Atlantic's property. All copies of such Information in
written, graphic or other tangible form shall be returned to Bell Atlantic upon
request. Unless such Information was previously known to BBT free of any
obligation to keep it confidential or has been or is subsequently made public by
Bell Atlantic or a third party, it shall be kept confidential by BBT, shall be
used only in the filling of orders, or in performing otherwise hereunder, and
may be used for other purposes only upon such terms as may be agreed upon in
writing by Bell Atlantic.

CHOICE OF LAW. The construction, interpretation and performance of this
Agreement shall be governed by and construed in accordance with the domestic
laws of the Commonwealth of Virginia.

COMPATIBILITY INFORMATION. Compatibility information is that technical
information, including but not limited to software interfaces, required to
design equipment and/or software which is functionally interconnectable with
Bell Atlantic's network and the Material supplied by BBT hereunder. Should the
interface information not be available from other sources without additional
cost to Bell Atlantic, BBT for a period of ten (10) years after providing such
Material shall supply, at no charge, such compatibility information to such
Material to Bell Atlantic within thirty (30) days of a request from Bell
Atlantic.

COMPLIANCE WITH LAWS. BBT shall comply with all applicable federal, state,
county and local laws, ordinances, regulations and codes (including procurement
of required permits or certificates) in BBT's performance hereunder,
irrespective of whether a specification is furnished. This includes, but is not
limited to, compliance with the Occupational and Safety Health Act of 1970 as
amended, the Small Business Investment Act of 1958 as amended, the Hazardous

<PAGE>

regulation affecting safety and health, including applicable "right to know"
laws and regulations. If Material, Services or containers furnished are required
to be constructed, packaged, labeled or registered in a prescribed manner, BBT

state or local laws and regulations, including but not limited to compliance
with the Hazard Communication Standard by furnishing applicable Material Safety
Data Sheets and any other required notices to Bell Atlantic on or before the
date of delivery of the associated Material, service or container. BBT agrees to
defend, indemnify and hold harmless Bell Atlantic for any loss, damage, penalty,
fine, or liability sustained because of BBT's noncompliance.

CONTINGENCY. Neither of the parties shall be held responsible for any delay or
failure in performance hereunder caused by fires, strikes, embargoes,
requirements imposed by Government regulation, civil or military authorities,
acts of God or by the public enemy or other similar causes beyond such party's
control. However, BBT's delay or failure to perform shall not be excused by a
default of any of its subcontractors, suppliers, or Lucent unless such default
arises out of causes beyond the control of BBT and its subcontractor, supplier
and Lucent and without the fault or negligence of any of them, and unless the
supplies or services to be furnished by such subcontractor, supplier or Lucent
are not obtainable from other sources on commercially reasonable terms. If such
contingency occurs, the party injured by the other's inability to perform may
elect to: (a) terminate this Agreement or part thereof as to Material and/or
Services not already received; (b) suspend this 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 or
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, (b) shall be deemed selected.

CONTINUING AVAILABILITY. BBT agrees to offer for sale to Bell Atlantic, for a
period of five (5) years after the expiration date of this Agreement,
functionally equivalent maintenance, replacement, and repair parts. Such parts
shall be priced at the then current Agreement price, or if no such Agreement
exists, at a price agreed upon by BBT and Bell Atlantic. In addition, should BBT
decide, during the Term, to discontinue manufacturing systems of Material BBT
shall give at least one (1) year prior written notice to Bell Atlantic of such
manufacture discontinuance. In the event BBT fails to continue to supply
Material and parts or provide advance notification prior to discontinuing
manufacture of Material and BBT is unable to obtain another source of supply


                                       4

for Bell Atlantic, then such inability shall be considered noncompliance with
this Section and, in addition to all other rights and remedies at law or in
equity, Bell Atlantic may require BBT, without obligation or charge to Bell
Atlantic, to provide Bell Atlantic with the technical information or any other
rights required so that Bell Atlantic can manufacture, have manufactured or

components purchased by BBT on the open market disclosing the part number, name
and location of the supplier, and price lists for the purchase thereof; and

any software licensed or otherwise acquired by Bell Atlantic from BBT hereunder.

deliver the Material and/or complete the performance of Services ordered
hereunder within the time specified or in accordance with agreed upon schedules,
or in the event BBT is in breach or default of any other term, condition or
provision of this Agreement and if such breach or default [******************

all other rights and remedies provided hereunder or at law or in equity, Bell
Atlantic shall have the right

with this Agreement, BBT agrees to administer engineering complaints in
accordance with Bellcore Technical Reference TR-EOP-000230, Guidelines for

BBT agrees to defend, indemnify and hold harmless Bell Atlantic for any loss,

Atlantic or Bell Atlantic's customers or the employees of either: (i) based on
any claim by any person for personal injury or death that occurs in the course
or scope of employment of such person by Bell Atlantic or Bell Atlantic's
customers and that arises out of Material or Services furnished under this
Agreement, or (ii) arising from or relating to BBT's contract with Lucent.

BBT is and shall be deemed to be for all purposes, an independent contractor.
BBT shall select its employees, agents and subcontractors, if any, and such

supervision and control of BBT, not Bell Atlantic. BBT hereby acknowledges
responsibility for full payment of wages and other compensation to all

Services under this Agreement, and for full compliance with all laws, rules and
regulations involving, but not limited to, employment of labor, hours of labor,
working conditions, and payment of taxes, such as unemployment, social security
and a new payroll after taxes, including applicable contributions from its
employees, agents, and subcontractors required by law. It is the expressed
intent of this Agreement that the relationship of BBT to Bell Atlantic shall be
solely that of independent contractor and not that of a joint venture,
partnership, or any other joint relationship.

infringement of any U.S. patent, trademark, copyright, trade secret or other
proprietary interest based on the manufacture, use or sale of any Material,
Services or equipment furnished to Bell Atlantic under this Agreement or in
contemplation of this Agreement. BBT shall defend, indemnify and hold harmless
Bell Atlantic and Bell Atlantic's customers for any loss, damage, expense or
liability that may result by reason of any such infringement or


                                       8

<PAGE>





claim, except where such infringement or claim arises solely from BBT's
adherence to Bell Atlantic's written instructions or directions which involve
the use of merchandise or items other than (1) commercial merchandise which is
available on the open market or is the same as such merchandise, or (2) items of
BBT's origin, design or selection; and Bell Atlantic shall so indemnify BBT in
such excepted cases. Each party shall defend or settle at its own expense, any
action or suit against the other for which it is responsible under this Section.
Each party shall notify the other promptly of any claim of infringement for
which the other is responsible, and shall cooperate with the other in every
reasonable way to facilitate defense of any such claim. Should any of the
Material, Services or equipment furnished to Bell Atlantic hereunder or in
orders placed hereunder, or in the operation hereof, become the subject of a
claim of any infringement of a patent, trademark, copyright, trade secret, or
other proprietary interest, BBT shall, at its expense, and at BBT's option,
either (i) procure for Bell Atlantic the right to continue using the Material,
Services or equipment, or (ii) replace or modify the same so that they become
non-infringing. If Seller's good faith effort to accomplish (i) or (ii) fails,
then Seller will refund to Bell Atlantic the full purchase price of the
infringing items.

INSIGNIA. Upon Bell Atlantic's written request certain of Bell Atlantic's
trademarks, trade names, insignia, symbols, decorative designs, or evidences of
Bell Atlantic's inspection (hereafter "Insignia"), will be properly affixed by
BBT to the Material furnished. Such Insignia will not be affixed, used or
otherwise displayed on the Material furnished or in connection therewith without
Bell Atlantic's written approval. The manner in which such Insignia will be
affixed must be approved in writing by Bell Atlantic. Material rejected or not
purchased by Bell Atlantic which utilized such Insignia shall have all such
Insignia removed prior to any sale, use or disposition thereof. BBT agrees to
indemnify and hold Bell Atlantic harmless from any claim, loss or damage arising
out of BBT's failure to do so. This Section shall in no way modify provisions
relating to the Section "BUYER'S INFORMATION".

INSPECTION. Unless Bell Atlantic gives BBT written notice to the contrary, BBT
shall notify Bell Atlantic or Bell Atlantic's agent when the Material is ready
for inspection and Bell Atlantic or Bell Atlantic's agent shall be given
reasonable opportunity to inspect the Material at any time prior to shipment
under Quality Program Specifications listed in Appendix D. Inspection or failure
to inspect on any occasion shall not affect Bell Atlantic's rights under the
Section "WARRANTY" or other provisions of this Agreement. BBT shall make
available at no additional cost to Bell Atlantic, such production testing
facilities, labor, data, specifications, procedures and such other documents,
and assistance as necessary for Bell Atlantic or Bell Atlantic's agent to
perform inspection. In addition, BBT shall make available to Bell Atlantic or
Bell Atlantic's agent, at no additional cost, data obtained through BBT's normal

routines which show results of BBT's inspection, tests and audits of Material as
specified in the Quality Program Specifications. Such data shall be sufficient
to demonstrate that the Material meets all quality and reliability requirements.

INVOICING FOR STOCKS. If Bell Atlantic requests, for reasons other than covered
by the Section "CONTINGENCY", that shipment be postponed beyond the date shown
on an order, BBT may invoice Bell Atlantic as of the original scheduled delivery
date for Material manufactured hereunder, if it has been inspected and approved
by Bell Atlantic or Bell Atlantic's Agent (provided inspection has been
specified).

LATE DELIVERY. If BBT does not deliver any Material [********************
*************] set forth in the applicable order, then, provided that such
delay is not attributable to the fault of Bell Atlantic, its employees or
agents (who are not also agents of BBT), or to reasons excused under the
Section titled "Contingency," Bell Atlantic may take any or all of the
following actions without prejudice to any other remedies available to it
at law, in equity or under this Agreement (i.e., default):
[******************************************************************************

LIABILITY, INSURANCE, INDEMNITY. BBT agrees to indemnify and save Bell Atlantic
harmless from any liabilities, claims, or demands (including the costs, expenses
and reasonable attorney's fees on account thereof) that may be made: (1) by any
third person for injuries, including death to persons or damage to property,
including theft, resulting from BBT's negligent or otherwise wrongful acts or
omissions, or those of persons furnished by BBT hereunder; (2) by any third
person for injuries, including death to persons or damage to property, caused by
any Material supplied by BBT hereunder in a defective or unreasonably dangerous
condition; or (3) under Worker's Compensation, or similar employer-employee
liability acts, against Bell Atlantic by persons provided by BBT. BBT agrees to
defend Bell Atlantic at Bell Atlantic's request, against any such liability,
claim or demand. The foregoing indemnification shall apply whether BBT or Bell
Atlantic defends such suit or claims. The parties agree to cooperate in the
defense or settlement of concurrent or joint claims, to use their best efforts
to agree privately on the

                                       10


<PAGE>






sharing of fault and the defense of claims, and, if necessary, to litigate the
issue of comparative fault and/or contribution in a tribunal or proceeding
independent of claimant. BBT's liability for indemnification shall be based on
the comparative fault of BBT compared to other persons, including Bell Atlantic.
Neither party shall be bound by a settlement made by the other to which it has
not consented. Bell Atlantic agrees to notify BBT promptly of any written claims
or demands against Bell Atlantic for which BBT is responsible hereunder. BBT
shall maintain, during the term thereof, all insurance and/or bonds required by
law, including but not limited to:

(1)      Commercial General Liability Insurance, on an Occurrence Basis,
         including, but not limited to (premises-operations, broad form
         property damage, products/completed operations, contractual
         liability, independent contractors, personal injury) with limits of
         at least $500,000 combined single limit for each occurrence.

(2)      Automobile Liability, Comprehensive Form, with limits
         of at least $500,000 combined single limit for each

(5)      Professional Liability, Errors and Omissions, with limits of not less
         than $1,000,000 per occurrence.

BBT agrees that BBT, BBT's insurer(s) and anyone claiming by, through, under or
in behalf of BBT shall have no claim, right of action or right of subrogation
against Bell Atlantic or Bell Atlantic's customers based on any loss or
liability insurable under the foregoing insurance. BBT shall be prepared, prior
to the start of work, to furnish certificates or adequate proof of the foregoing
insurance. BBT shall also require its subcontractors, if any, who may enter upon
Bell Atlantic premises to maintain similar insurance and to agree to furnish
Bell Atlantic, if requested, certificates or adequate proof of such insurance.
Certificates furnished by BBT or its subcontractors shall contain a clause
stating that "Bell Atlantic is to be notified in writing at least thirty (30)
days prior to cancellation of, or any material change in, the policy." BBT shall
maintain insurance, as required by this Agreement, through insurance carriers
which have and maintain an A.M. Best rating of B+VII or greater. Bell Atlantic
and its Parent and Affiliates shall be named as an


                                       17

additional insured to the insurance policies required under this Agreement and
this shall be so evidenced upon the Certificate(s) of Insurance.

NONEXCLUSIVE MARKET RIGHTS. It is expressly understood and agreed that this
Agreement does not grant to BBT an exclusive privilege to sell or otherwise
provide Bell Atlantic any or all products or Services of the type described in
this Agreement. It is, therefore, understood that Bell Atlantic may contract
with other manufacturers and suppliers for the procurement of comparable items.
Bell Atlantic shall determine, at its own discretion, the extent to which Bell
Atlantic will market, advertise, promote, support or otherwise assist in further
offerings of the Material. BBT agrees that purchases by Bell Atlantic under this

NON-WAIVER. Bell Atlantic's failure at any time to enforce any of the provisions
of this Agreement or any right or remedy available hereunder or at law or
equity, or to exercise any option herein provided will in no way be construed to
be a waiver of such provisions, rights, remedies or options or in any way to
affect the validity of this Agreement. The exercise by Bell Atlantic of any
rights, remedies or options provided hereunder or at law or equity shallnot
preclude or prejudice the exercising thereafter of the same or any other rights,
remedies or options.

Section "WARRANTY", BBT agrees to provide repair service on all Material ordered
hereunder for a period of ten (10) years after the expiration of this Agreement.
Bell Atlantic will return Material to be repaired under this Section to a
location designated by BBT, and unless otherwise agreed upon by BBT and Bell
Atlantic, BBT shall ship the repaired Material which meets the specifications
established in the Section "SPECIFICATIONS OR DRAWINGS", within thirty (30) days
of receipt of the defective Material. With the concurrence and scheduling of
Bell Atlantic, repair may be made by BBT on site. If Material are returned to
BBT for repair as provided for in this Section, and are determined to be beyond
repair, or repair costs are expected to exceed eighty percent (80%) of the cost
of a replacement, BBT shall so notify Bell Atlantic. If requested by Bell
Atlantic, BBT will sell to Bell Atlantic a replacement at the current Agreement
price or, if no such Agreement exists, at a price agreed upon by BBT and Bell
Atlantic. Further, BBT shall, unless otherwise directed by Bell Atlantic, return
to Bell Atlantic said un-repairable Material with full accountability and at no
cost(s) to Bell Atlantic, other than applicable return transportation charges.
If directed by Bell Atlantic, BBT shall take all the necessary steps to dispose
of said un-repairable Material, in a manner consistent with all applicable
Federal, State and Local laws and environmental regulations, with full salvage
value rendered to Bell Atlantic. All transportation charges associated with the
return of un-repairable Material to Bell Atlantic will be borne by Bell
Atlantic. Replacement and repaired Material shall be warranted as outlined in
the section "WARRANTY". It is expressly understood and agreed that this
Agreement does not grant BBT any exclusive privilege to repair any or all of the
Material purchased hereunder for which Bell Atlantic may require repair; and BBT
and Bell Atlantic may contract with others for these Services. In addition, BBT
authorizes Bell Atlantic and any qualified repairer with whom Bell Atlantic may
contract to perform out of warranty repairs on all Material purchased under this
Agreement. All transportation charges for, and risk of in-transit loss or damage
to, Material returned to BBT for repair under this section will be borne by Bell
Atlantic. All transportation charges associated with the return of such repaired
and replacement Material to Bell Atlantic will be borne by Bell Atlantic.
Charges for repairs under this Section are covered in Appendix A.

provisioning and maintenance activities shall be considered by BBT to be
confidential or proprietary.

SEVERABILITY. In the event that any one or more of the provisions contained
herein shall, for any reason, be held to be unenforceable in any respect, such
unenforceability shall not affect any other provision of this Agreement, but

          in accordance with the applicable Commercial Specifications.











(c) In the event that the parties shall fail to reach agreement on any such
change to be made, then in addition to all other rights and remedies at law or
in equity or otherwise, Bell Atlantic shall have the right to cancel this
Agreement and any or all purchase orders affected by such change.

STORAGE OF PAID FOR STOCKS. All Material invoiced to Bell Atlantic in accordance
with the Section, "INVOICING FOR STOCKS," shall be marked conspicuously as Bell
Atlantic's property, and safely stored by BBT separated from any other Material
stocks, and shall be shipped out as ordered by Bell Atlantic. BBT's total
liability under this Section is for [*************************] per order. BBT
assumes responsibility for any loss or damage to such Material while stored by
BBT. Seller shall advise in writing of the specific location where Material is
stored and of any subsequent removal of the Material from one building to
another, or from one part of the same building to another and give such advance
notice as may be requested by Bell Atlantic. BBT agrees, upon request by Bell

conveyance of such Material, free from liens and encumbrances, together with any
other document such as a bailment agreement, warehouse receipt, lease (on
storage space), mortgage, deed of trust, or surety bond as Bell Atlantic may
deem necessary to secure title in such Material as against third parties, all of
which documents shall be in a form acceptable to Bell Atlantic.

SUBCONTRACTING. BBT shall not, without Bell Atlantic's prior written approval,
subcontract any portion of the work to be performed hereunder. Subassembly work
such as circuit board stuffing or printed circuit board assembly and etching are
not considered subcontracting work under this Section.

TECHNICAL SUPPORT. Bell Atlantic shall be entitled to ongoing technical support,
including field service and assistance provided, however, that the availability
or performance of this technical support service shall not be construed as
altering or affecting BBT's obligations as set forth in the Section titled
"WARRANTY" or as elsewhere provided for in this Agreement. BBT's technical
support via telephone as well as field service technical support shall be
provided to Bell Atlantic without charge.

TERMINATION OF ORDER.  Bell Atlantic may [*******************************]

BBT with respect to such ******************************************************
*******************************************************************************
or salable to BBT's other customers in process at the date of giving notice of 
termination, less any salvage value thereof.  [***********************]  If 
requested, BBT agrees to substantiate such costs with proof satisfactory to 
Bell Atlantic.
[***********************************************************************].

TESTING. All Material shipped shall receive testing to demonstrate functionality
and quality levels at least equivalent to Material embedded in systems. Testing
and burn-in intervals should be of sufficient duration so that infant mortality
failure rate of Material shipped is no greater than [*******] the predicted
steady-state failure rate. Testing performed should provide verification of
operability as completely as possible with current manufacturing test
capabilities. This should 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) should normally be included as one of the
test steps. Material returned for repair must be tested in a simulated use
environment as part of the repair process. Returned Material which are found to
be operational upon their receipt should be tested under [******************] to
identify thermostatic devices which may have been the cause for return. Return
and repair results data shall be made available to Bell Atlantic or Bell
Atlantic's agent.

TITLE AND RISK OF LOSS. Title and risk of loss to the Material purchased by the
Bell Atlantic under this Agreement shall vest in the Bell Atlantic when the
Material has been delivered at the F.O.B. point. If this Agreement calls for
additional Services such as unloading, installation, or the like to be performed
after delivery, BBT shall retain risk of loss and damage to the Material until
the additional Services have been performed. Notwithstanding the above, if BBT


                                       24

<PAGE>









is expressly authorized to invoice Bell Atlantic for stocks prior to shipment,
title to those stocks shall vest in Bell Atlantic upon payment of the invoices.

by Lucent Technologies, Inc. and Bell Atlantic in support of the Material. In
addition, if requested by Bell Atlantic: (a) provide instructors and the
necessary instructional material of BBT's standard format to train Bell
Atlantic's personnel in the installation, planning and practices, operation,
maintenance, repair and marketing of Material furnished hereunder. These classes

Bell Atlantic and at costs agree upon by both parties; or, at the option of Bell
Atlantic, (b) provide Bell Atlantic with training modules or manuals and any
necessary assistance, covering those areas of interest outlined in (a) of this
Section, sufficient in detail, format and quantity to allow Bell Atlantic to
develop and conduct a training program

TRANSPORTATION. Material ordered by Bell Atlantic shall be shipped by BBT,
F.O.B. origin, Durham, North Carolina, Freight Collect, with instruction to the
carrier to forward the original freight bill to the Bell Atlantic's designated
agent as specified on the Carrier Routing Provisions described in Appendix D.
Deviation from these instructions must be authorized by Bell Atlantic's
Transportation Organization. Excess transportation charges resulting from the
BBT's failure to comply with these instructions will be billed back to the BBT.
With respect to Material ordered F.O.B. Origin prepaid, i.e., RPS, BBT agrees to
add freight charges as a separate line item on BBT's invoice for Material, and
further agrees, if requested, to substantiate such charges by providing Bell
Atlantic with the original freight bill, RPS shipping list or a copy thereof.

WARRANTY. BBT warrants to Bell Atlantic that Material furnished will be new,
safe, free from defects in design, material and workmanship. BBT also warrants
that the Material will conform to and perform in accordance with the
specifications and drawings set forth in this Agreement for a period of
[***********************************************]. At the time of delivery such
Material shall be free of any security, interest or other lien or any other
encumbrance whatsoever. Inspection, examination, testing, acceptance, or use of
Material hereunder shall not affect BBT's obligation under this Section
"WARRANTY", and such warranty shall survive inspection, examination, testing,
acceptance, and use. Defective Material will, at Bell Atlantic's option either
be returned to BBT for repair or replacement with risk of in-transit loss and
damage borne by Bell Atlantic and transportation charges paid by Bell Atlantic,
or be repaired or replaced by BBT on site. Unless otherwise agreed upon by BBT
and Bell Atlantic, BBT shall complete repairs and ship the

                                       25

repaired Material within thirty (30) days of receipt of defective Material or at
the option of Bell Atlantic, ship replacement Material within fifteen (15) days

of in-transit loss and damage and shall prepay and bear the cost of
transportation charges for shipments to Bell Atlantic of repaired or replaced
Material. If requested by Bell Atlantic, BBT shall begin on-site repairs within
fifteen (15) days after verbal notification is given BBT by Bell Atlantic. BBT's
obligations as set forth in the Section "PRODUCT CHANGES" shall be in addition
to BBT's obligations hereunder. If Material returned to BBT or made available to
BBT on site for repair, as provided for in this Section, is determined to be
beyond repair, BBT shall promptly so notify Bell Atlantic and, unless otherwise
agreed to by BBT and Bell Atlantic, ship replacement Material without charge
within fifteen (15) days of such notification. Any replacement, repair,
modification, installation or other service performed by BBT shall be warranted
for a period of six (6) months or for the remainder of the unexpired period of
the warranty whichever is longer based upon the date performance of the service
is completed and accepted by Bell Atlantic. BELL ATLANTIC'S SOLE AND EXCLUSIVE
REMEDIES FOR BREACH OF WARRANTY ARE SET FORTH ABOVE IN THIS SECTION, EXCEPT AS
PROVIDED IN THE SECTION LIABILITY, INSURANCE, AND INDEMNITY. THE ABOVE WARRANTY
IS IN LIEU OF ALL OTHER WARRANTIES, INCLUDING WARRANTIES OF MERCHANTIBILITY AND
FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE HEREBY EXPRESSLY EXCLUDED.

WORK HEREUNDER. It is understood that visits by BBT's representatives or BBT's
suppliers' representatives for inspection, adjustment or other similar purposes
in connection with Material and/or Services purchased hereunder shall for all
purposes be deemed "work hereunder" and shall be at no charge to Bell Atlantic

         5.3 The rights granted in Section 5.2 shall apply to Material and Parts
which are to be supplied by Company to Bell Atlantic pursuant to the FSN
Agreement and/or the Companion Agreement. Company agrees not to exercise the
rights granted in Section 5.2 prior to a material failure by Supplier to supply
Materials or Parts and the expiration of any applicable cure period, and only
for those Materials or Parts which Supplier fails to supply. The rights granted
in Section 5.2 shall terminate five years after Company first ships to a
customer any Materials or Parts manufactured by Company pursuant to Section 5.2,
however, Company shall retain rights under Section 5.2 for as long as necessary
to provide maintenance, replacement or repair parts to customers as required
under the FSN Agreement and the Companion Agreement. In the event that the

furnishing by Company, Company shall pay to Supplier a royalty fee on each
Material or Part manufactured pursuant to Section 5.2 which Company furnishes
under the FSN Agreement or the Companion Agreement. The royalty fee shall be
[*******************************************************] from the sale of such
Materials and Parts, and shall be payable on [*******************************]
in which such Materials or Parts are shipped.

         5.6 In the event Company elects to exercise the rights granted in
Section 5.2 following a failure by Supplier to materially supply Materials and
Parts, and within two (2) years after such failure Supplier again wishes to

any orders under this Amendment, the defaulting party shall initiate corrective
action to remedy such breach or default or provide the affected party a schedule
acceptable to the nonbreaching party for correcting such breach or default
within ten (10) days after the giving of written notice to the defaulting party
thereof by the nonbreaching party. In the event the breach or default is not
corrected within thirty (30) days after the giving of written notice to the
defaulting party thereof by the nonbreaching party or within the agreed upon
schedule, whichever is later, then, in addition to its right to pursue all other
rights and remedies at law, equity or otherwise, the nonbreaching party shall
have the right to cancel this Amendment and/or any such orders in whole or in
part without charge, obligation or liability whatsoever, except as to payment
for Material already accepted by Bell Atlantic prior to such notice pursuant to
the FSN Agreement.

         6.2 The parties agree that the clause in the Agreement entitled
"Termination of Purchase Order" shall apply only to purchase orders terminated
by Company for convenience and without cause.

         6.5 The parties acknowledge that there are several clauses in the
Agreement which require matters to be referred to the Executive Team for
resolution before a party can exercise rights under such clause. Such clauses
include, by example and not limitation, "Later Delivery/Liquidated Damages and
Cancellations." Notwithstanding anything contained in the Agreement to the
contrary, the parties agree that, except as expressly required in this
Amendment, referral to the Executive Team shall not be required for either party
to exercise any right or remedy set forth in this Amendment; it being the intent
that the only prerequisites to the exercise by either party of any right or
remedy under this Amendment shall be the express notice, cure period, or other
conditions or requirements set forth in this Amendment.

         6.6 In the event either party shall be in default or breach of this
Amendment, the parties agree that they will cause the Executive Team to attempt,
in good faith, to resolve the situation within a reasonable period of time given
the circumstances (however, in no event to exceed ten (10) calendar days). In
the event the Executive Team is unable to resolve the situation within such
period of time, the parties will retain all legal rights and remedies.

Material or Parts or to purchase Material or Parts from any source other than
Supplier, except as provided in the Agreement or Article 5 of this Amendment.

reduce the amount of its commitment forecast to Supplier under this Amendment;
and (b) Company shall have no obligation to order the quantity of Material under
any commitment forecast delivered to Supplier in the event Supplier shall be in
default or breach of this Amendment in any material respect.

         10.4 In return for Supplier's agreement to provide the discounts set
forth in Section 10.3, the parties agree that the cost reduction benefits set
forth in the clause "Value Analysis-Engineering and Cost Reduction" of the
Agreement shall not apply to purchases of Material under this Amendment;
provided, however, that Supplier does agree to count any such purchases of
Material by Company under this Amendment, towards the cost reduction volume
thresholds defined in said clause for purposes of determining the cost
reductions available to Company for purchases of Material not made under this
Amendment.

         10.5 If during the term of the Agreement, Company is provided more
favorable pricing from Supplier due to cost reduction efforts, or for any other
reason, Supplier acknowledges that Company will receive this pricing for
Material supplied by Company under this Amendment, subject to prior Executive
Team review and approval. However, in the event that the pricing set forth in
this Amendment is the most favorable, Company will not extend this pricing to
any other customer without prior written approval from Supplier.

15.0     WARRANTY

         15.1 Material purchased under this Amendment shall be warranted in
accordance with the clause of the Agreement entitled "Warranty" except that
repaired, modified, and/or serviced Material shall be warranted for the
[*******************************************************].

         15.2 For all purposes of this Amendment, the clause "Warranty" in the
Agreement is hereby amended as follows:

         (a) The last sentence of the second paragraph is amended to provide,
"If requested by Company, Supplier shall begin on-site repairs within an average
of three (3) days after verbal notification is given Supplier by Company."

         (b) Supplier warrants that Supplier has the right to grant to Company
the Software and other licenses granted under this Amendment. Supplier further
warrants to Company that the furnished Software shall be free from defects in
design, that it will conform to the applicable specifications, and that it will
operate satisfactorily in the system environment in which it is initially
installed. Defective Software will be corrected or replaced after notification
is given to Supplier by Company. Supplier, at its option, will undertake to
either correct or replace the defective Software without charge at the location
where it is installed in accordance with corrective action prescribed for the
applicable Severity Code (per Appendix C to the General Purchase Agreement in
effect between Bell Atlantic and Company), or, at Supplier's option, provide a
refund or credit of the original license fee; provided, however, that Supplier
may elect to provide a credit to Company only where Company reasonably
determines the credit to be of value.

  16.0            CHANGE CONTROL PROCESS

         16.1 Supplier acknowledges that Bell Atlantic may submit written
requests to Company to request changes or revisions to hardware and software to
be furnished under the FSN Agreement and, to the extent Bell Atlantic's request
involves Material, Company shall immediately notify Supplier (a "Change Control
Request"). Change Control Requests requiring [*********************************]
will be handled in the normal change control process. Change Control Requests
[*******************************************************] will be negotiated by
the parties and will be performed under this process provided that the parties
reach mutually satisfactory agreement on requirements, Headcount Years, price
and delivery schedule. Any resulting Software shall be licensed to Company under
the provisions of Article 5 without payment of any additional license fees or
charges other than charges for the development work as provided herein.



                                       20



<PAGE>




         16.2 Within fifteen (15) days (or a different period if mutually agreed
to by the parties) following receipt of a Change Control Request from Company,
Supplier shall provide a written response to Company specifying: (i) the
specifications for the work to be performed; (ii) the work schedule for the
proposed work; (iii) a firm price quote for the work, and associated new
hardware unit prices (if any) for the new Material, (iv) the number of Headcount
Years required, and (v) the impact, if any, on the delivery date of the Material
to be modified; provided, however, that (x) the fees payable by Company for any
such Change Control Request shall not exceed
[***************************************************************], and (y) the
Headcount Years proposed shall be commercially reasonable.
[*******************************************************] may be adjusted by
Company in December of each calendar year up to the amount of any change in the
Producer Price Index for Telecommunications Systems, [*************************]
during the preceding twelve (12) month period. This limitation shall not,
however, apply to Major Changes.

         16.3 If Supplier's response is approved in writing, Supplier will
proceed with the work. Supplier shall not be obligated to perform any requested
changes or revision to Material in advance of written approval from Company. In
the event that Supplier commits resources to the implementation of a Change
Control Request without prior written authorization, Company shall not be
charged for such work and such work shall not relieve Supplier of its
obligations to meet previously agreed upon schedules. For purposes of this
Amendment, each Change Control Request response approved in writing by Company
shall constitute a formal change to this Amendment modifying the prices,
functionality and/or schedules as addressed therein, and any hardware or
Software developed pursuant to such a request shall fall within the definition
of the term "Material."

         16.5 Supplier agrees to pay to Company as a Software [*******] Fee,
[***************] of the amount of fees provided by Company to Supplier under
this Section 16.5 for changes to Software, only. The Software [*******] Fee due

[**************] of the payment of the fees for the Software changes made by
Company to Supplier under this Section 16.5.


  17.0            ADDITIONAL SOFTWARE

         17.1 The parties enter into this Amendment with the mutual
understanding that it is Company's intention to continue feature and function
development beyond Release 2.1. As Supplier develops Additional Software,

                                       21


<PAGE>




Supplier will seek and utilize input from Bell Atlantic and Company other
customers.

         17.2 Supplier will make available to Company any generally available
Additional Software upon mutually agreeable prices and terms and conditions.
[******************************************************************************
******************************************************************************].

         17.3 Additional Software shall be licensed to Company at fees no less
favorable than those extended to any other Supplier customer, under comparable
terms and conditions (i.e., comparable scope of license and usage rights).


  18.0            LATE DELIVERY

         18.1 Supplier acknowledges that Bell Atlantic may assess [*****] to
Company under the [******] Agreement for [*************] if products and
services are not delivered within [***************] of the delivery date set
forth in the applicable order. In addition to any other rights and remedies

Atlantic may recover from Company [****************] for the portion of the
order that is late in the following cumulative amounts:
[******************************************************************************
*******************************************************************************
*******************************************************************************
*************] that the shipment remains past due until the earlier of the
effective date of cancellation (if Bell Atlantic exercises its right to cancel
the applicable order) or the date delivery is made. Company's
[*****************] per order, shall not exceed the price of products and/or
services not delivered.

         18.2 Company and Supplier acknowledge that as a result of the means by
which the parties will be working together to deliver products to Bell Atlantic,
that it may be extremely difficult to determine which party is at fault for late
deliveries to Bell Atlantic prior to general availability of hardware and
software. Accordingly, if Bell Atlantic notifies Company of its assessment of
[****************] for late delivery, Company shall promptly notify Supplier
thereof.


                                       22

<PAGE>







         Supplier agrees to share with Company any [*********************] by
Bell Atlantic for late deliveries under the FSN Agreement as follows: (a) if
Company is [*********************] for late delivery for any hardware and/or
software (whether or not such hardware or software includes Material to be
furnished by Supplier hereunder) and the agreed upon delivery date is prior to
the general availability date of such hardware and/or software,
[***************************] will be paid by Supplier and
[**************************] will be paid by Company, regardless of which party
caused the late delivery; (b) if Company is [*****************] as a result of
late delivery of Material by Supplier hereunder and the agreed upon delivery
date for such Material is after the general availability date of such Material,
all such [**************] shall be borne solely by Supplier and Supplier agrees
to pay to Company any and all such [*************]. After the general
availability date of Material, Supplier shall not be held accountable for
[*************] assessed by Bell Atlantic to Company if Supplier has delivered
the Material on or before the agreed upon delivery date for the applicable
Company purchase order.

         18.3 Company shall invoice Supplier for [*************] due and owed by
Supplier under Section 18.2 within a commercially reasonable period of time and
Supplier agrees to pay all such invoices in full within thirty (30) days from
the date of such invoices. At Company's option, Company may withhold against any
Supplier invoices then outstanding payment in an amount equal to any accrued and
due but unpaid [**************] under Section 18.2, until such time as said
[**************] are paid by Supplier.

         18.4 Bell Atlantic may cancel any purchase order, in whole or in part,
at any time after [************************************] set forth in the
applicable order. In the event that Bell Atlantic cancels any or all of such
purchase orders, Company may cancel any related purchase orders placed under
this Amendment. Upon such cancellation, Supplier shall pay Company any
[****************] accrued under Section 18.2 but unpaid as of the date of
cancellation. The amount of any canceled purchase orders shall be credited
against any unfulfilled commitment forecasts or other committed purchases of
Supplier under this Amendment.

         18.5 In the event Bell Atlantic exercises its rights under the FSN
Agreement to defer or cancel delivery of all or any portion of a purchase order
for failure to obtain required regulatory approvals, Company shall have the
corresponding right to defer or cancel delivery of all or any portion of related
purchase orders for Material upon notice to Supplier. Upon such notice, Supplier
will not ship any Material covered by such orders until Company is authorized by
Bell Atlantic and Company instructs Supplier to do so. Supplier shall have no
liability under Section 18.2 for shipments delayed under this Section 18.5.

[********************************************************] set forth in Exhibit
D ("Nonconformance"). In the event Bell Atlantic notifies Company of any
Nonconformance ("Notice of Nonconformance"), Company shall promptly provide
notice thereof to Supplier. If a Nonconformance is not remedied within the
[*****************************] set forth in Exhibit D ("Event of
Nonconformance"), Company is [********************] to Bell Atlantic for such
delay for each Event of Nonconformance in accordance with Exhibit D for each day
of Nonconformance following the Notice of Nonconformance.

         19.2 Supplier and Company agree to jointly work all aspects of
development and deployment to deliver conforming Software releases to Bell
Atlantic on a timely basis. Supplier agrees to share with Company any

follows: (a) [********************************] shall be paid by Company; and
(b) [*****************************] shall be paid by Supplier.

         19.3 Company shall invoice Supplier for [**************] due and owed

         19.4 In addition to its right to recover [*****************], Bell
Atlantic may terminate the FSN Agreement for default if (a) either [*********]
specified in Exhibit D or a [************************] which Bell Atlantic
believes to be material to the functioning of the ASE is subject to an Event of

[*******************************************] payable by Supplier under Articles
18, 19, and 20 of this Amendment and, subject to the
[****************************************] provided in Section 21.1(a), any and
all outstanding amounts will be paid by Supplier to Company within thirty (30)
days after the date of such expiration or termination, as applicable. Upon such
payment, if any, Supplier shall have no further liability for Nonperformance
[*************************************] under said Articles.

  22.0            MANUFACTURING CAPACITY

         22.1 Supplier warrants that it has established and covenants that it
will maintain during the Term, sufficient manufacturing capacity for Material to
ensure that Bell Atlantic's Beta Test Date, its FSA Date, and any commercial FSN
deployment will not be jeopardized due to Supplier delivery delays.

  23.0            JOINT COST REDUCTION COMMITMENT

         23.1 This Section 23.1 is included as explanation of the Company and
Supplier cost reduction commitments, and should not be viewed as further
reductions to the price modifications as defined in the Article 17, Price
Modification to Achieve Model Price Per Home Passed, of this Amendment.


                                       27

 23.2 Supplier agrees to work with Company to jointly achieve the required cost
reduction that will support a price reduction to Bell Atlantic of
[********************************************************], when using the
standard Bell Atlantic FSN model. This required cost reduction will entail a
commitment by both Supplier and Company to enter into joint design work to
achieve this cost reduction, regardless of the volume level projections. It is
the goal of the cost reduction efforts that this cost reduction will be achieved
by January 1998.

         23.3 Both Company and Supplier agree to a baseline view of the cost
reduction impact on price. This view, using the Bell Atlantic FSN model,
supports the following reductions in price / HP as the baseline:

         (a)      HDT Integration - [********] (Company Responsibility)

 (b)     New Integrated ONU - [********] (Shared Responsibility:
                           Company - [********]; Supplier - [********])

         The ONU cost reduction and resultant price impact baseline view is
allocated between Company and Supplier proportional to each parties share of
components in the current ONU, evaluated with the current ONU pricing. Both
Company and Supplier agree to update this baseline view and the contribution
required from each party as the joint design work progresses and becomes better
defined.

         23.4 The new Integrated ONU will require both Company and Supplier to
commit resources to a single design. To accomplish this goal, both Company and
Supplier accept the concept of an integrated joint design team. This effort will
lead to some circuit packs and other equipment having design contributions from
both parties. Both Company and Supplier commit their commercially reasonable
best efforts to establish and complete appropriate commercial arrangements in
support of this mutual effort within three (3) months from the Effective Date of
this Amendment. Company and Supplier acknowledge that the level of integration
required to meet these cost reduction targets integrates intellectual property
and manufacturing rights of both parties and it is the intent of Company and
Supplier to assign such rights prior to the commencement of development
activities. Any disputes arising from this integration will be resolved by the
Executive Team prior to any assignment of such rights.

25.0     TRAINING/LAB MATERIAL

         25.1 Supplier acknowledges that Bell Atlantic requires the delivery and
installation of [*******************************] by the dates set forth in
Exhibit D to this Amendment. Company agrees to provide Supplier with a forecast
and purchase orders for Material required for such systems, and Supplier agrees
to accept such purchase orders and ship such Material in sufficient time to
enable Company to deliver and install the laboratory test systems on time.

         25.2 Supplier will provide to Company [*********************] as
described as "Lab System 1" in Appendix D to the FSN Agreement, free of charge,
which Company shall supply to Bell Atlantic, at Company's sole discretion, for
either training or laboratory testing purposes. The configuration of the system
shall be mutually agreed to by all the parties and shall be sufficient to meet
the requirements of Bell Atlantic. Supplier agrees to upgrade this system and
will provide new features and functionalities as each becomes available up
through Release 2.1.
[******************************************************************************.


  26.0            PUBLIC INTERFACES

         26.1 Supplier agrees to provide Company and Bell Atlantic with any
public interface specification documentation and reasonable amounts of support
to resolve any questions Company or Bell Atlantic may have regarding these
interface specifications as they pertain to Bell Atlantic's FSN deployment or
the ASE.


  27.0            TESTING AND QUALITY

  27.1  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).


                                       29

<PAGE>






         (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 [********************]. The testing duration will be
such that 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
[**************************] the steady-state reliability level. That is, the
instantaneous failure rate at cut over shall be less than or equal to
[**************************] 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 [**************************] 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. Bell
Atlantic 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 [***********] to
identify thermostatic devices which may have been the cause for return. Return
and repair results data shall be made available to Bell Atlantic or Bell
Atlantic'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.

         27.2 Unless Company gives Supplier written notice to the contrary,
Supplier shall notify Company when each installment of Material is ready for
inspection and Company and Bell Atlantic (or its agent) shall be given

                                      30

<PAGE>

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 Amendment. 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 Bell Atlantic or Bell Atlantic's
agent to perform the inspection. In addition, Supplier shall make available to
Company and Bell Atlantic or Bell Atlantic'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.

         27.3 Commitment to quality is a primary requirement of this Amendment
and as used herein shall mean conformance to the terms, conditions and
specifications of this Amendment. Supplier will ensure continued quality
improvement in the Materials covered in this Amendment. Supplier will
demonstrate commitment to a "Quality Improvement Process" by providing (i) a
published statement of its quality policy signed by an officer of the company;
(ii) an established means of measuring and reporting customer satisfaction;
(iii) a quality training and awareness program; (iv) a continuous Quality
Improvement Process; (v) an established means of monitoring conformance to
requirements for Material and/or Services; and (vi) an established in-coming
"Material Quality Inspection Program." Further, Supplier shall implement and
document a quality system(s) that meets the requirements in ISO 9000 and
Bellcore documents, GR-1252-CORE, "Quality System Generic Requirements for
Hardware," and TR-NWT-000179, "Quality System Generic Requirements for
Software." Upon Company's written request, Supplier agrees to allow Company and
Bell Atlantic or Bell Atlantic's agent to conduct on-site reviews at the
Supplier's hardware manufacturing and software development facility(s) to verify
compliance with requirements. Supplier also agrees to develop corrective action
plans for any quality system deficiencies that may be detected during these
periodic on-site reviews, and submit these to the Company and Bell Atlantic or
Bell Atlantic's agent within thirty (30) days after the review. Further,
Supplier agrees to use its commercially reasonable best efforts to implement
these corrective action plans within six (6) months after the review.

         27.4 Supplier agrees to abide by and meet all applicable provisions of
the Quality and Reliability Specifications in Appendix I to the FSN Agreement.
Any existing or anticipated noncompliance by Supplier with such Specifications
will be disclosed by Supplier to Company in writing on or before July 26, 1996 
to enable Company to notify Bell Atlantic thereof pursuant to the FSN Agreement.
Such notice from Supplier shall include a written schedule

                                      31

<PAGE>

pursuant to which Supplier shall cure such instances of noncompliance. To the
extent Bell Atlantic waives any obligation of Company to comply with such
Specifications for a stated period of time under this FSN Agreement, Company
agrees to waive such obligation for Supplier to comply under this Amendment for
the corresponding period of time. The parties acknowledge that Bell Atlantic's
acquiescence in or agreement to a schedule under which Supplier or Company shall
cure any noncompliance shall not constitute a waiver by Bell Atlantic.


  28.0            TROUBLE REPORTS

         28.1 Supplier acknowledges that Bell Atlantic must reduce its Access
Subnetwork Trouble Report Rate by at

agrees to assist Company in supporting Bell Atlantic's Overall Objective by
providing reliability and other information, including but not limited to
Failures in Time (FIT) Rates for Material, and will provide additional support
and expertise which may contribute to the specification and achievement of Bell
Atlantic's objectives if requested by Company, at no cost to Company.

  29.0            GENERAL FSN SUPPORT

         29.1 The parties acknowledge that the FSN Agreement and concomitant
Appendices contain performance obligations which are intended to be performed by
Company and Supplier individually and, in some instances, Company and Supplier
together. With respect to those obligations of the FSN Agreement and Appendices
related to content and/or Material to be provided by Supplier, Supplier agrees
to provide the same in a timely manner and to cooperate with and support Company
generally in the provision to Bell Atlantic and the Bell Atlantic Affiliates of
