300 CONSTITUTION DRIVE OFFICE LEASE  AGREEMENT TO TERMINATE

THIS 300 CONSTITUTION DRIVE OFFICE LEASE AGREEMENT TO TERMINATE (the "Agreement") is made as of September 19, 2003, by and between TYCO ELECTRONICS
CORPORATION, a Pennsylvania corporation ("Landlord"), and INTERWAVE COMMUNICATIONS, INC., a Delaware corporation ("Tenant").

RECITALS:

A.    Landlord
and Tenant entered into that certain 300 Constitution Drive Office Lease dated as of November 24, 1999 ("Original Lease"), pursuant to which Landlord has
leased to Tenant certain premises commonly known as 312 Constitution Drive, Building I, Menlo Park, California ("Premises"). The Lease was amended by the Amendment of Office Lease dated as of
September 14, 2001 ("Amendment"). The Original Lease, as amended by the Amendment, shall hereinafter be referred to as the "Lease."

B.    Landlord
and Tenant now desire to terminate the Lease upon the terms and conditions hereinafter set forth. Unless otherwise defined herein, capitalized terms used in this
Agreement shall have the meanings ascribed to such terms in the Lease.

NOW, THEREFORE, the parties agree as follows:

1.Incorporation of Recitals.The Recitals set forth above are incorporated in full into this Agreement by this
reference.

2.Term.Subject to the terms and conditions contained in this Agreement, the Lease shall terminate as of
June 30, 2003 ("Termination Date").

3.Termination Fee.As consideration for Landlord's entering into this Agreement, Tenant shall pay to Landlord,
in immediately available funds, a termination fee in the amount of One Million Nine Hundred Thousand Dollars ($1,900,000) ("Fee"). Tenant shall pay the Fee to Landlord in nineteen (19) equal
installments of $100,000 each. Tenant shall pay to Landlord the first installment of the Fee on or before October 1, 2003, and Tenant shall pay to Landlord the subsequent installments of the
Fee on or before the first day of each month thereafter to and including April 1, 2005. If Tenant shall fail to pay to Landlord any monthly installment of the Fee on or before the fifth day of
the month when due, and such failure shall continue for five (5) days following written notice thereof from Landlord to Tenant, at Landlord's option, Tenant shall pay to Landlord upon demand a
late payment charge in an amount equal to five percent (5%) of the overdue installment, which the parties agree is a reasonable estimate of Landlord's damages arising therefrom; provided, however,
that following the third occasion on which Landlord shall have given to Tenant written notice of an overdue installment in accordance with the foregoing provision, if Tenant shall fail to pay to
Landlord any monthly installment of the Fee on or before the fifth day of the month when due, at Landlord's option, Tenant shall pay to Landlord upon demand such late payment charge in an amount equal
to five percent (5%) of the overdue installment. In addition to the foregoing provisions, if Landlord shall be entitled to impose upon Tenant a late payment charge in accordance with the foregoing
provisions by reason of Tenant's failure to make timely payment of any monthly installment of the Fee, Landlord shall have the right, by written notice given to Tenant after the date as of which
Landlord shall be entitled to impose such late payment charge, to declare the entire unpaid portion of the Fee to be due and payable on the date that is seven (7) days following the date of
such written notice to Tenant, in which case, unless Tenant shall make payment of such overdue monthly installment of the Fee within such 7-day period, Tenant shall be obligated to make
immediate payment to Landlord of the entire unpaid portion of the Fee.

4.Surrender of Premises.Landlord acknowledges that Tenant vacated and surrendered possession of the Premises
to Landlord on or before the Termination Date, and that Landlord has accepted possession of the Premises in the condition required under the Lease. Accordingly, Landlord and Tenant shall have no
further rights, obligations or claims with respect to each other arising from the Lease, except as provided in this Agreement and except for Landlord's indemnity obligations under
Section 6.4(b) of the Lease, and except for Tenant's indemnity obligations under Section 6.4(a) of the Lease.

5.Abandoned Property.In addition to any rights Landlord may have under the Lease or this Agreement, Landlord,
at its sole option, may deem any furniture, fixtures, shelving, cabinets, tables, equipment,
lighting, parts, inventory or personal property in, on or attached to the Premises and remaining in or on the Premises after the Termination Date ("Abandoned Property"), whether or not belonging to
Tenant, to be abandoned, and Landlord may dispose of the Abandoned Property as Landlord in its sole discretion deems appropriate. Tenant shall not be entitled to any proceeds received by Landlord as a
result of the disposition of the Abandoned Property. Tenant waives, to the greatest extent permitted by law, all of its rights under California Civil Code Sections 1980,et
seq., as the same may be amended from time to time, and any related and successor statutes thereto.

of the Termination Date:



7.Reinstatement.In the event that all or any part of any payment or performance by Tenant under this Agreement
shall be avoided or recovered directly or indirectly from Landlord as a preference, fraudulent transfer or otherwise under the U.S. Bankruptcy Code or any other bankruptcy, insolvency or similar laws,
all of Landlord's rights under this Agreement shall be reinstated with respect to the payment or performance so avoided or recovered as though such payment had never been made or such obligation had
never been performed.

8.Successors in Interest and Assigns.This Agreement is binding on Landlord and its legal representatives,
successors and assigns, and each of their officers, directors, shareholders, partners, employees, managers, independent contractors, agents and attorneys ("Landlord Entities"), and on Tenant and its
authorized and unauthorized subtenants, legal representatives, successors and assigns, and each of their officers, directors, shareholders, partners, employees, managers, independent contractors,

expressly waives any and all rights and benefits otherwise conferred by the provisions of Section 1542 of the California Civil Code and any other similar provision of any other jurisdiction,
