weeks delay.

states, than each item invoiced must indicate final shipping destination. Each
invoice shall be paid within thirty (30) days of receipt unless it is disputed
by Verizon Wireless.

order to assure prompt remittance:

                  (1)      Verizon Wireless' Order number

                                  each applicable taxing jurisdiction.
                  (5)      Transportation costs.
                  (6)      Other charges (if applicable).
                  (7)      Final total cost.
                  (8)      Contract number.

         SMSI shall defend Verizon Wireless, at Verizon Wireless' request,
against any such liability, claim or demand. The foregoing indemnification shall
apply whether SMSI or Verizon Wireless defends such suit or claim and whether
the death, injury or property damage is caused by the sole acts or omissions of

hereunder. Verizon Wireless agrees to notify SMSI promptly of any written claim
or demands against Verizon Wireless for which SMSI is responsible hereunder.

directly or indirectly out of or in connection with any claim that the Software
violates any patent issued as of the date of this agreement, trademark,
copyright and any other intellectual or industrial property right of third
parties, finally awarded in any such claim, suit or proceeding. SMSI shall have
no liability for infringement based on (a) use of other than the current release
of the Software, (b) modification of the Software without SMSI's written
consent, (c) the combination or use of the Software with any other software,
equipment, product, device, item or process not furnished by SMSI or not
contemplated under this Agreement, if such infringement would have been avoided

unmodified form, (d) Verizon Wireless's continued infringing activities after
being notified thereof or after being informed of modifications that would have
avoided the infringement or, (e) Verizon Wireless's use of the licensed product

from SMSI's indemnity obligation by the previous sentence.

9.3      Verizon Wireless agrees to indemnify, defend, and hold SMSI harmless
from and against any and all actions, suits, claims, liabilities, damages,

other party, ought reasonably to be treated as confidential.

10.3     Exceptions. The foregoing shall not prevent either Party from
disclosing Confidential Information which: (a) is or becomes a part of the
