8.1. Product Orders. Distributor shall, during the term hereof, order
Products or Spare Parts in accordance with all of the terms and conditions of
this Agreement. Each order placed by Distributor for any Products or Spare
Parts (a "Product Order") shall be deemed to incorporate all of the terms
and conditions of this Agreement, and any terms and conditions of such Product
Order which are in addition to or inconsistent with the terms and conditions of
this Agreement shall be deemed stricken from such order. Distributor shall
place all Product Orders in writing for Products with Tekelec at its address
written above. In addition, each Product Order shall specify the Products
which Distributor desires to purchase and a requested shipment date for each
Product (the "Requested Shipment Date"). Requested Shipment Date shall be
during the term hereof, except that Tekelec may, in its sole discretion, accept
a Product Order during the term hereof which has a Requested Ship Date after
the expiration or termination of this Agreement, in which event all terms and
conditions of this Agreement shall apply to such shipment, but under no
circumstances will such shipment be deemed to be, or be construed as being, a
renewal or extension of this Agreement.

8.2. Confirmation; Shipment Dates. All Product Orders submitted by
Distributor shall be subject to acceptance by Tekelec in writing and shall not
be binding until the earlier of such acceptance or shipment, and any acceptance
by shipment shall be binding only as to the portion of the Product Order

submitted by Distributor in accordance with this Agreement within ten (10) days
from actual receipt by Tekelec of such Product Order, provided that Tekelec
shall not be obligated to accept any Requested Shipment Date which is less than
three (3) months from the date of the relevant Product Order (an "Expedited
Shipment Date"). If Tekelec will not accept or reject any product order within
said ten (10) days, Tekelec shall be deemed to have accepted it. In the event
that Tekelec does desire to accept any Expedited Shipment Date specified in a
Product Order, Tekelec shall so indicate in writing, but may specify therein an
alternative shipment date. Such alternative shipment date shall be deemed the
Requested Shipment Date for purposes of a Product Order unless Distributor
rejects such alternative shipment date by written notice to Tekelec within ten
(10) days from receipt of the written notice containing such alternative
shipment date. In the event that Distributor rejects any alternative shipment
date for any Products specified in such written notice within such ten (10)-day
period, such Products shall be deemed stricken from the Product Order in which
such Products were initially ordered by Distributor, unless Tekelec and
Distributor agree on a new shipment date.

8.3. Shipment. Tekelec shall ship to Distributor each Product ordered from
Tekelec pursuant hereto on or before the Requested Shipment Date for such
Product. In the event that Tekelec is unable to ship any Product, as described
in Section 8.2 of this agreement, from the Requested Shipment Date for such
Product, Distributor shall have the right to terminate that portion of the
Product Order relating to such Product by written notice to Tekelec, which
termination shall only be effective if such notice is received by Tekelec prior
to the date on which such Product is shipped by Tekelec or identified to the
Product Order by marking, description or otherwise. Upon termination of any
portion of a Product Order by Distributor with respect to a particular Product
in accordance with this Section 8, Tekelec shall promptly return to Distributor
all amounts, if any, paid by Distributor with respect to such Product. In this
instance, the Distributor will be relieved from all terms and conditions
described in Section 8.5 and Tekelec will reimburse to the Distributor the
lessor of (i) [**] of the purchase price of that portion of the product which is
canceled under the provisions of this Section 8.3 and which has not been
accepted by Distributor and (ii) the actual penalties assessed the Distributor
by the end user for such cancellation. In the event that Distributor does not
exercise its cancellation rights with respect to any Product pursuant to this
Section 8, Tekelec shall remain obligated to ship such Product to Distributor in
accordance with all of the applicable provisions of this Agreement.

The shipping and delivery dates applicable to each Product Order will be agreed
upon by Tekelec and Distributor and set forth in such Product Order. In the
event that Tekelec exceeds the agreed upon delivery date by twenty (20) business
days, through no fault of Distributor and for reasons other than those covered
in the Section entitled Force Majeure and for reasons other than Tekelec's
Right to Delay, Cancel or Allocate as defined in Section 8.4, then in addition
to all other rights and remedies at law or in equity or otherwise,
Distributor may have Tekelec

7
8

apply to that portion of Product Order which has not been delivered the
following discounts off the purchased price for such delayed portion:

Number of Weeks
Beyond agreed to Delivery Date Amount of Discount
------------------------------ ------------------

1 [**]
2 [**]
3 [**]
4 [**]
5 [**]

In no event shall such discount(s) exceed [**] of the purchase price of the
Product Order.

Should Distributor be encumbered by Project Cancellation fees higher than those
in this Section 8, Tekelec shall use best efforts to secure a bond covering the
difference between the contracted cancellation fee obligated by Distributor
and the schedule in this Section 8.

DISTRIBUTOR'S RIGHT TO COLLECT DISCOUNTS AND PENALTIES FOR DELAYED SHIPMENTS OR
CANCEL ANY PORTION OF A PRODUCT ORDER WITH RESPECT TO UNSHIPPED OR UNIDENTIFIED
PRODUCTS PURSUANT TO THE SECTION 8 SHALL CONSTITUTE DISTRIBUTOR'S SOLE AND
EXCLUSIVE REMEDIES ARISING OUT OF OR RELATED TO TEKELEC'S FAILURE TO SHIP OR
MAKE DELIVERY WITHIN ANY SPECIFIC TIME FROM THE REQUESTED SHIPMENT DATE FOR
SUCH PRODUCTS.

8.4 Tekelec's Right to Delay, Cancel or Allocate. Notwithstanding
Tekelec's obligations under Section 8 hereof, Tekelec reserves the right to
cancel any orders placed by Distributor and accepted by Tekelec as set forth
above, and shall have the right to refuse, cancel or delay shipment to
Distributor when Distributor is delinquent in payments, when payment for a
shipment has not been arranged to Tekelec's reasonable satisfaction, or when
Distributor has failed to perform its obligations under this Agreement. Should
orders for Products exceed Tekelec's available inventory, Tekelec will
allocate its available inventory on a basis Tekelec deems equitable, in its
sole discretion, and without liability to Distributor on account of the method
of allocation chosen or its implementation. Tekelec also reserves the right to
cancel any orders for any Products of discontinued or changed Products (as set
forth in Section 9 below) without liability of any kind to Distributor or to
any other person. No delay, refusal or cancellation under this Section 8 will
be deemed a termination (unless Tekelec so advises Distributor) or breach of
this Agreement by Tekelec.

8.5 Distributor's right to Cancel. Distributor shall have the right,
during the term hereof, upon written notice to Tekelec given prior to any
Requested Shipment Date, to cancel shipment or to delay shipment to a later
date within the Delivery Term of all or a specified portion of the Product
Order to be shipped by Tekelec to Distributor on such Requested shipment Date.
Cancellation or rescheduling within sixty (60) days of the Requested Shipment
Date shall subject Distributor to cancellation or rescheduling charges based on
the total dollar value of the canceled or rescheduled Products and the number of
days prior to the Requested Shipment Date that written notice of cancellation
or rescheduling is received. Cancellation or rescheduling charges will be
calculated in accordance with the following schedule:

Cancellation Period Charge (% of Value)

31 - 60 days [**]
15 - 31 days [**]
Less than 15 days [**]

8.6 Partial Shipments. If stated on a Product Order and as mutually
agreed between Distributor and Tekelec, Tekelec shall be entitled to make
partial shipments of Products covered by a Product Order as such Products
become available for shipment and may invoice Distributor separately for each
such partial shipment,

8
9
provided, however, that at the time of such partial shipment or before Tekelec
shall notify Distributor of the date(s) when Tekelec anticipates making
additional partial shipments or shipping the balance of the Product Order.
Partial shipment of Products covered by a Product Order shall not relieve
Distributor from its obligation hereunder to accept future shipments of
Products by Tekelec in satisfaction of such Product Order, except to the
limited extent that Distributor has properly canceled the portion of such
Product Order relating to such future shipment as set forth in Section 8 above.

8.7 Shipment: Risk of Loss. Delivery of the Products to Distributor
shall be F.O.B. Tekelec's point of shipment. Title (except as to Software) and
risk of loss or damage with respect to any of the Products to be delivered to
Distributor shall pass from Tekelec to Distributor upon delivery of such
Products to the carrier for shipment to Distributor, subject to Tekelec's right
to stop delivery of Products in transit. Unless otherwise specified by
Distributor by written notice given at least thirty (30) days prior to the
Requested Shipment Date, all Products ordered by Distributor shall be shipped
by Tekelec to Distributor's principal place of business specified above. Upon
proper notice, Distributor may have Tekelec ship some or all of the Products to
destinations other than Distributor's principal place of business. Unless
specified in Distributor's Product Order, Tekelec will select the mode of
shipment and the carrier. All transportation, handling and insurance charges
for any of the Products from Tekelec's point of shipment to destination shall be
borne by Tekelec. Such insurance shall be reasonably acceptable to Distributor.

8.8 Entry Into Territory. Distributor shall have sole responsibility for
arranging any permits, notices, bonds, inspections or other requirements for
entry of Products into the Territory. Distributor shall be solely responsible
as described in Section 6.8 of this agreement.

8.9 Acceptance by Distributor. Distributor shall have thirty (30)
business days following receipt of the Products in which to notify Tekelec of
any discrepancy in the shipment. Tekelec will use best efforts to correct such

thereof. After this five (5) day period, all rights and penalties as set forth
in Section 8.3 shall apply.

infringement of any copyright in the Products). Without limiting the generality
of the foregoing, Distributor agrees that it will not attempt to register, or
assist any other party (other than Tekelec or its designee) in attempting to
register, any trademark, trade name or other proprietary right with any public
or private authority without the express and unambiguous prior written consent
of Tekelec. Unless otherwise mutually agreed in writing, Distributor will not
attach any additional trademarks, logos or trade designations to the Products.
Distributor will not affix any Tekelec trademark, logo or trade name to any

and payment of mutually agreed consideration, Distributor may affix its
trademark, logo or trade name to Product covered under this Agreement.

disapprove any materials which make use of the Tekelec trademarks that
Distributor uses or proposes to use. Upon expiration or termination of this
Agreement, Distributor will: (i) cease all display, advertising and use of all
of Tekelec's names, marks, logos and designations; (ii) return or destroy, at
Tekelec's sole discretion, all materials where Tekelec's name appears; and
(iii) will not thereafter use, advertise or display any name, ▇▇▇▇ or logo
which is, or any part of which is, similar to or confusing with any such
designation associated with Tekelec.

13.4. Nature of Software Distribution. With respect to any Product that
is a software Product, and to the extent any other Product contains software,
this Agreement only grants to Distributor a license to transfer such Products
to Distributor's customers, and does not transfer any right, title, or interest
in or to any such software to Distributor. Notwithstanding any "purchase" or
"sale" or similar language contained herein, Distributor acknowledges that such

of the following: (i) modify such Product so that it ceases to be infringing or
wrongful; (ii) procure the right for the parties to continue distributing such
Product; or (iii) prepare a non-infringing substitute Product. If, after

4.1. Product problems are categorized to reflect the initial impact or
potential impact on the customer application.

fault report to functioning of the system
fix delivery to and do not seriously affect
site service to the customer
----------------------------------------------------------------------

* Response objective interval is time between report of problem and
delivery of fix

4.2 NSD will maintain a Customer Service Request (CSR) database to record
and track customer problems (a MADIC Module). This database is updated
to reflect the current status of each problem or request.

36
37
4.3 NSD's Technical Services group is responsible for recording customer's
requests for assistance; tracking and managing a problem or request
through resolution; and implementing corrective actions if necessary.

4.4 Telephone Consultation is performed to confirm warranty and the severity
of the problem or issues. During the initial trouble shooting phase, the
symptoms of the reported problem are confirmed for accuracy.

4.5 If during the consultation with the customer the problem is deemed a
Critical or a Major problem the escalation procedure is implemented. The
NSD management will help facilitate acquiring any resource needed to
resolve the problem.

4.6 If during the trouble shooting phase it is determined that a unit, part,
board, etc., is needed to resolve the problem, the Technical Services
Representative issues the customer a Return Material Authorization (RMA)
number to allow for the unit, part, or board to be returned for repair,
replacement, upgrade, etc.

4.7 A System Problem Report (SPR) is opened when problem resolution requires
Design Engineering support. Engineering classifies the SPR as either a
Critical, Major, Minor, or Enhancement SPR.

4.8 If the remote troubleshooting does not resolve the problem, NSD may
request to send a Field Service Engineer to the customer's site to assist
with troubleshooting.

4.9 A Technical Services Representative will continue to monitor and track the
problem until the situation is resolved. If an RMA and/or SPR was
generated from the CSR the CSR remains open until the associated RMA
and/or SPR is closed. The CSR database is routinely updated with
information concerning the resolution of the issue.

4.10 CSR closure requires a description of the problem resolution as part of
the CSR record, and the customer's concurrence of that description. Both
the resolution description and the name and date of customer
representative agreeing to the solution should be recorded in the action
field of the CSR. Statistical data on problem occurrences and maintenance
activities is maintained in the database.
