exceptions describing the damage before signing; and

     (b) at the time of delivery, request the carrier to either inspect the loss
or damage and forward to Supplier a signed exception report outlining the extent

Supplier; and

     (c) within ten days after delivery, inspect the damaged material and notify
Supplier whether Company will (i) accept it at a mutually agreed lower price
reflecting the transportation damage (if Supplier had the risk of loss) or the
manufacturing defect, or (ii) reject it. Rejected lots shall be set aside by
Company pending disposition by Supplier as soon as reasonably possible but no
later than sixty days following delivery, after which time any such damaged
Consigned Material remaining undisposed of shall be deemed to be abandoned and
Company may dispose of it as it sees fit without any obligation to Supplier.

As to concealed transportation damage or hidden manufacturing defects in
material, if after withdrawal of Consigned Material from Consigned Material
Storage, Company discovers concealed transportation damage or defective
material, Company shall notify Supplier within five days of such discovery, take
reasonable steps to preserve evidence of how such damage occurred and take all
actions provided for in subparagraph (c) above. Where Consigned Material Storage

owner of such other premises to comply with the procedure set forth in this
clause.

     (10) Termination - Company may at any time, and without cause terminate any

process not to exceed the next two (2) weeks beyond the maximum Authorized Stock
based on the then current Weekly Demand Report; and (4) Supplier's purchase
price of raw material not to exceed the next two (2) weeks beyond the maximum
Authorized Stock based on the then current Weekly Demand Report (not usable in
Supplier's other operations or salable to Supplier's other customers). If
requested, Supplier agrees to substantiate the manufacturing costs for work in
process and the purchase price of the raw material with proof satisfactory to
Company. Upon such termination, the parties shall meet promptly to determine the
finished material, work in process and raw material for which Company is
responsible as set forth above. Supplier shall ship the finished material (to
the extent not already in transit or in Consigned Material Storage) and raw
materials to Company pursuant to shipping schedules agreed upon by the parties.
As to work in process, Supplier shall, at Company's option, ship it to Company

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.

or damage and forward to Supplier a signed exception report outlining the extent
of loss or damage, or issue a written waiver of inspection and forward it to
Supplier; and

     (c) within ten days after delivery, inspect the damaged material and notify
Supplier whether Company will (i) accept it at a mutually agreed lower price
reflecting the transportation damage (if Supplier had the risk of loss) or the
manufacturing defect, or (ii) reject it. Rejected lots shall be set aside by
Company pending disposition by Supplier as soon as reasonably possible but no
later than sixty days following delivery, after which time any such damaged
Consigned Material remaining undisposed of shall be deemed to be abandoned and

process not to exceed the next two (2) weeks beyond the maximum Authorized Stock

requested, Supplier agrees to substantiate the manufacturing costs for work in
process and the purchase price of the raw material with proof satisfactory to
Company. Upon such termination, the parties shall meet promptly to determine the
finished material, work in process and raw material for which Company is
responsible as set forth above. Supplier shall ship the finished material (to

ORDERING COMPANIES - Lucent Technologies Inc. or any affiliated corporation,
partnership, or venture, both U.S. and foreign, as may be designated in writing
by Lucent Technologies Inc., may order under this Agreement. For the purpose of
this Agreement, the term "Company" 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 Technologies Inc. Any contract or order issued under this Agreement will
be a contractual relationship between the ordering Company and the Supplier and
Supplier shall look only to the ordering Company for performance of the ordering
Company's obligations under such contract or order.

OZONE DEPLETING CHEMICALS - Supplier 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. Supplier hereby
warrants that the material furnished to Company will conform to all 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
currently causing the manufacturing vendor to reduce and will, in an expeditious
manner, eliminate, or, as applicable, have its manufacturing vendor eliminate
the use of ODCs in the manufacture of the material.

If the material furnished by Supplier under this Agreement is manufactured
outside the United States, Supplier 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
Company the attached ODC Content Certification. The ODC Content Certification
must be signed by Supplier'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 Supplier's vendors and any other vendors in producing
components or other products incorporated into the material sold to Company.

Supplier is responsible to obtain information on the ODC content of all
components and other products acquired to manufacture the material and to
