                          AMENDED AND RESTATED SUBLEASE

      This Amended and Restated Sublease (the "Sublease"), dated, for
identification purposes only, March 24, 2005 to be effective as of the "Closing
Date" (as defined below)(the "Effective Date"), is made by and between CONEXANT
SYSTEMS, INC., a Delaware corporation (herein called "Sublessor"), and MINDSPEED
TECHNOLOGIES, INC., a Delaware corporation (herein called "Sublessee").

      A. Replacement. Sublessor and Sublessee are parties to that certain
Sublease dated as of June 27, 2003 (the "Original Sublease") covering
approximately 189,729 square feet of rentable area, including the entire east
tower, approximately 10,027 square feet of a two-story bridge connecting the
east tower with the west tower and approximately 2,667 square feet of rentable
area in the west tower (the "Old Subleased Premises"). Prior to the Effective
Date, (1) Sublessor has remeasured the east tower, the bridge and the west
tower, (2) Sublessee has surrendered to Sublessor any portion of the Old
Subleased Premises located in the west tower and (3) Sublessor was the tenant
under that certain Lease dated as of August 18, 1998 (the "Original Master
Lease") by and between Deutsche Bank, AG, as landlord, and Sublessor, as tenant.
As of the Effective Date, the Original Master Lease is being replaced with that
certain Lease dated to be effective as of the Effective Date by and between
IDF/KBS 4000 MacArthur, LLC, a Delaware limited liability company ("Master
Lessor"), as landlord, and Sublessor, as tenant (the "Master Lease"). Pursuant
to Section 2.3 of the Original Sublease, in the event that Sublessor obtained a
"Replacement" (as defined in the Original Sublease), Sublessee is required to
execute documentation to evidence Sublessee's agreement to be bound by any
change in or additions required in connection with the Replacement. Accordingly,
Sublessor and Sublessee agree that, effective upon the date that Sublessor sells
the buildings in which the Old Subleased Premises are located to Master Lessor
(the "Closing Date"), this Sublease shall be effective and the Original Sublease
shall have no further force or effect thereafter.

      B. Premises. Effective as of the Effective Date, Sublessor hereby leases
to Sublessee and Sublessee leases from Sublessor for the term, at the rental and
upon all of the conditions set forth herein the entire east tower, together with
the two-story bridge connecting the east tower and the west tower (collectively,
the "East Tower"), and containing in the aggregate approximately 193,137 square
feet of rentable area (the "Subleased Premises"). Sublessee acknowledges that
the Subleased Premises are all of the East Tower which, as of the Effective
Date, will be owned by Master Lessor. Notwithstanding the foregoing, if, at any
time after the Effective Date, Sublessee is leasing less than the entire East
Tower under this Sublease, then all references in this Sublease to the
"Subleased Premises" shall mean that portion of the East Tower then leased by
Sublessee under this Sublease. Sublessee acknowledges that, as of the Effective
Date, Sublessor and Master Lessor are also entering into a lease for the entire
west tower (the "West Tower") which contains approximately 180, 310 square feet
of rentable space (the "Other Lease").

      C. Term. The term of this Sublease shall commence on the Effective Date
(the "Sublease Commencement Date"), and shall end on the scheduled expiration of
the term (including any extension term resulting from Sublessee's exercise of
its option pursuant to Section E.a. below) of the Master Lease, unless sooner
terminated pursuant to any provision hereof. Subject to Section

                                       1
<PAGE>
E.w. below, this Sublease shall terminate upon the expiration or earlier
termination of the Master Lease.

Notwithstanding the foregoing or anything to the contrary in this Sublease, the
following shall apply:

                  (i) Sublessee recognizes that Sublessor is not in a position
      to render any of the services or to perform any of the obligations
      required of Master Lessor by the terms of the Master Lease (including
      without limitation those set forth in Section 8.1(b), (c)(ii) and/or
      (d)(i) and/or Section 11.2 of the Master Lease). Therefore, despite
      anything to the contrary in this Sublease, Sublessee agrees that
      performance by Sublessor of its obligations

                                       6
<PAGE>

      under this Sublease is conditioned on performance by the Master Lessor of
      its corresponding obligations under the Master Lease, and Sublessor will
      not be liable to Sublessee for any default of the Master Lessor under the
      Master Lease.

                  (ii) Sublessee will not have any claim against Sublessor based
      on Master Lessor's failure or refusal to comply with any of the provisions
      of the Master Lease unless that failure or refusal is a result of
      Sublessor's act or failure to act. Despite Master Lessor's failure or
      refusal to comply with any of the provisions of the Master Lease, this
      Sublease will remain in full force and effect and Sublessee shall pay all
      rent and all other charges provided for in this Sublease without any
      abatement, deduction or setoff so long as Sublessee's use and enjoyment of
      the Subleased Premises is not disturbed. Except as expressly provided in
      this Sublease, Sublessee agrees to be subject to, and bound by, all of the
      covenants, agreements, terms, provisions, and conditions of the Master
      Lease, as though Sublessee was the tenant under the Master Lease.

                  (iii) Whenever the consent of Master Lessor is required under
      the Master Lease, Sublessor agrees to use its reasonable, good faith
      efforts to obtain, at Sublessee's sole cost and expense, that consent on
      behalf of Sublessee. Whenever Master Lessor fails to perform its
      obligations under the Master Lease, Sublessor agrees to use its
      reasonable, good faith efforts to cause Master Lessor to perform such
      obligations on behalf of both Sublessor and Sublessee.

                  (iv) Sublessor agrees not to modify the Master Lease in a
      manner that materially adversely affects Sublessee's rights under this
      Sublease. Sublessee and Sublessor will each refrain from any act or
      omission that would result in the failure or breach of any of the
      covenants, provisions, or conditions of the Master Lease on the part of
      the Tenant under the Master Lease. Sublessor agrees to timely perform all
      of its obligations under the Master Lease, including, without limitation,
      the payment of all rent thereunder.

            r. Subordination. The provisions of Section 15.1 of the Master Lease
are hereby incorporated by reference herein as if set forth in full herein,
except that all references to "Landlord" therein shall be deemed references to
Sublessor herein, all references to "Tenant" therein shall be deemed references
to Sublessee herein, all references to the "Premises" therein shall be deemed
references to the Subleased Premises, all references to the "Lease" therein
shall be deemed references to this Sublease and the ten (10) business day period
therein is hereby amended to a five (5) business day period.

            s. Right of Entry. The provisions of Article 16 of the Master Lease
are hereby incorporated by reference herein as if set forth in full herein,
except that all references to "Landlord" therein shall be deemed references to
each of Sublessor and Master Lessor, all references to "Tenant" therein shall be
deemed references to Sublessee herein, all references to the "Premises" therein
shall be deemed references to the Subleased Premises, all references to the

            If to Master Lessor:     pursuant to Article 18 of the Master Lease.

            u. Brokers. Sublessor and Sublessee each represent and warrant to
the other party that no broker or finder can properly claim a right to a
commission or finder's fee based upon contacts between the claimant and the
warranting party with respect to the other party or the Subleased Premises.
Sublessee and Sublessor shall indemnify, defend and hold each other harmless
from and against any loss, cost or expense, including, but not limited to,
attorneys' fees and court costs, resulting from any claim for a fee or
commission by any other broker or finder in connection with the Subleased
Premises and this Sublease resulting from the indemnifying party's actions

            v. Special Provisions. Except as otherwise expressly provided below
in this subsection v., the provisions of this subsection v. shall apply with
respect to this Sublease:

                  (i) In the event of a conflict between the provision of this
Sublease and that certain Distribution Agreement (the "DA") between Sublessee
and Sublessor whereby Sublessee was spun-off from Sublessor on June 27, 2003,
the provisions of the DA shall apply.

                  (ii) Attached hereto as EXHIBIT C and incorporated herein is a
schedule of eight (8) categories of services, which Sublessee may elect
Sublessor to perform with respect to or for the benefit of the Subleased
Premises pursuant to the provisions of this clause (ii) (the "Additional
Services"). For the period from and after the Sublease Commencement Date through
June 26, 2005, Sublessor shall provide all of the Additional Services described
in items 1 and 3 through 8 of EXHIBIT C and Sublessee shall pay the Additional
Services fees attributable to such items set forth in EXHIBIT D as Additional
Rental. By March 31st of each year during the Term,

                                       8
<PAGE>

Sublessor shall deliver notice to Sublessee, which shall specify the categories
of Additional Services available for the year along with the estimated cost of
providing the Additional Services to the Subleased Premises. Such costs shall
reflect only the actual cost and expense incurred by Sublessor with respect to
providing such Additional Services, whether such Additional Services would be
provided by Sublessor's personnel or by an outside vendor. By April 30th of each
year during the Term, Sublessee shall provide Sublessor with notice as to which,
if any, of the categories of Additional Services Sublessee elects Sublessor to
provide during the ensuing "lease year" (i.e., the period from and after June 27
of one calendar year through June 26 of the following calendar year). Such
notice is irrevocable during the year such services are requested, except that
all Additional Services may be terminated by Sublessee in connection with the
expiration or sooner termination of this Sublease, so long as such termination
was not caused by a default by Sublessee. The cost of all Additional Services
elected by Sublessee to be provided shall be paid monthly by Sublessee together
with the payment of all Monthly Rental. The provisions of Sections 8.1(c) and
(d) of the Master Lease, as modified pursuant to Section E.i. above, shall apply
to the payment of all Additional Services. The parties agree that as long as
Sublessor has a cafeteria and/or auditorium at the Newport Beach Campus, then
access shall be provided to Sublessee as an Additional Service and that the
right to purchase Additional Services is personal to Sublessee and shall not be
offered to any subtenant or assignee of Sublessee.

Notwithstanding anything stated to the contrary in this Section E.v., if (a) the
Master Lease is terminated for any reason and this Sublease continues in effect
in accordance with the provisions of Section E.w. below, or (b) Sublessee is
required to attorn to any permitted mortgagee of Sublessor under the terms of
Section 15.2 of the Master Lease, then, effective upon the occurrence of either
of the events set forth in clauses (a) and (b) above, the provisions of this
Section E.v. shall no longer be effective and shall be void and unenforceable.

            w. Non-Disturbance and Attornment. If the Master Lease terminates
for any reason prior to the end of its term, then, notwithstanding anything
stated to the contrary herein (including, without limitation, the provisions of
Section E.v. herein, which shall no longer be effective), (i) Sublessee's use,
possession, and enjoyment of the Premises shall not be disturbed so long as
Sublessee is not then in default under this Sublease (unless such default is
waived by Master Lessor in its sole and absolute discretion), and (ii) effective
as of the termination of the Master Lease (the "Attornment Date"), this Sublease
shall automatically (without the need for any further action or documentation)
become a lease directly between Master Lessor, as landlord, and Sublessee, as
tenant, as if the Master Lessor were the landlord originally named in this
Sublease and this Sublease shall be subject to all of the terms and provisions
of the Master Lease to the extent incorporated herein by the terms of this
Sublease; provided, however, notwithstanding the foregoing, Master Lessor shall
not be bound by any future amendment or modification to this Sublease unless
Master Lessor consents to such amendment or modification in writing at the time
such amendment or modification is entered into. In such event, Sublessee hereby
covenants and agrees to attorn to Master Lessor (without any deductions or
setoffs except as expressly provided herein) as of the Attornment Date, and to
recognize the Master Lessor as the landlord under this Sublease; provided,
however, Sublessee shall not be liable for any acts, omissions or defaults of
Sublessor under the Master Lease other than any such acts, omissions or defaults
existing as of the Attornment Date which, with notice and/or lapse of time,
become an Event of Default by Sublessee under this Sublease; and provided,
further, that, so long as

                                       9
<PAGE>

Sublessee is not in monetary breach of this Sublease as of the Attornment Date,
in no event shall Sublessee be responsible for payment of rent due and payable
to Master Lessor by Sublessor prior to the Attornment Date. Master Lessor shall
not be liable for any acts, omissions or defaults of Sublessor, or the return of
any security deposit except for the security deposit actually paid to Master
Lessor, either in cash or by posting of a letter of credit, by Sublessor under
the Master Lease. Upon request by Master Lessor, Sublessee will execute a
document confirming the foregoing agreements by Sublessee. Sublessee hereby
acknowledges and agrees that upon the occurrence of the events set forth above
in clauses (i) and (ii) of this Section E.w., Sublessor shall automatically be
released from any further obligations under this Sublease to the extent first
arising after the Attornment Date. Notwithstanding the foregoing, if the Master
Lease is terminated as a result of a taking under Article 9 of the Master Lease,
this Sublease shall only continue between Master Lessor and Sublessee as to the
remaining portion of the Subleased Premises not subject to the taking.

            x. Right of First Refusal. Sublessor shall have the right of first
refusal during the Term of this Sublease to sub-sublease from Sublessee any
portion of the Subleased Premises that Sublessee desires to sub-sublease to a
third party (collectively, the "First Refusal Space") on the terms set forth in
this subparagraph w. In the event Sublessee receives a bona fide offer to
sublease the First Refusal Space or any portion thereof which Sublessee desires
to accept, Sublessee shall give Sublessor written notice thereof and of such
other terms on which Sublessee is willing to sublease such First Refusal Space
(or portion thereof). Sublessor shall have the right to sublease the First
Refusal Space or portion thereof specified in Sublessee's notice on the terms
set forth in Sublessee's notice and otherwise on the terms and conditions set
forth in this Sublease (except that, in such sub-sublease, the term "Sublessor"
as used in this Sublease shall be amended to refer to Sublessee, the term
"Sublessee" as used in this Sublease shall be amended to refer to Sublessor, the
term "Subleased Premises" as used in this Sublease shall be amended to refer to
such First Refusal Space or portion thereof which is the subject of Sublessee's
notice, the "Security Deposit" as used in this Sublease and any Additional
Rental payable under this Sublease shall be amended to be a straight-line pro
rata share for purposes of the sub-sublease, the "Sublease Commencement Date" as
used in this Sublease shall be amended to refer to the commencement date
specified in Sublessee's notice and the provisions of Section E.v.(ii) shall not
apply as between Sublessor and Sublessee with respect to such sub-subleased
space). If Sublessor desires to exercise the foregoing right, it shall do so, if
at all, by written notice to Sublessee given within ten (10) days after the date
of Sublessee's notice. If Sublessor fails to exercise the foregoing right within
the time and in the manner set forth herein, such right shall lapse and
thereafter not be exercisable by Sublessor as to the First Refusal Space or
portion thereof so offered, and Sublessee shall be free to sub-sublease the
space so offered to any third party, on terms no more favorable to the
sub-sublessee than those specified in Sublessee's notice; provided, however, if
any First Refusal Space previously offered to Sublessor as to which Sublessor
fails to exercise the foregoing right again becomes available for sub-sublease
during the Term (i.e., the third party to whom Sublessee sub-subleased the same
vacates or quits the same for any reason, and Sublessee desires to lease such
space again), then the foregoing right of first refusal shall again apply.

            y. Master Lessor as a Third Party Beneficiary. Sublessee
acknowledges and agrees that it has been advised that Master Lessor would not
permit Sublessor and Sublessee to enter into this Sublease without the
provisions of Sections E.w. and E.z. herein being enforceable

                                       10
<PAGE>

and binding against Sublessee and, in consideration of Master Lessor's entering
into the Master Lease and allowing Sublessor and Sublessee to enter into this
Sublease, Sublessee acknowledges and agrees that Master Lessor (and its
successors and assigns) shall be deemed a third party beneficiary of the
provisions of Section E.w. above and Section E.z. below with the full right and
power to enforce all of the provisions contained therein against Sublessee.

            z. Payment of Monthly Rental directly to Master Lessor. Upon written
request (the "Monthly Rental Direction") at any time by Sublessor, Sublessee
shall thereafter remit directly to Master Lessor all Monthly Rental payable by
Sublessee to Sublessor hereunder and any such amounts remitted to Master Lessor
shall be deemed paid to Sublessor. Following Sublessor's delivery of the Monthly
Rental Direction to Sublessee, Sublessee shall not be entitled to thereafter
remit Monthly Rental to Sublessor (notwithstanding any direction by Sublessor to
do so) without Master Lessor's prior written approval.

            aa. Election under Section 365(h)(1)(A)(ii) of the Bankruptcy Code.
Sublessee covenants and agrees that in the event this Sublease is rejected by
Sublessor in connection with any bankruptcy proceeding involving Sublessor,
Sublessee covenants and agrees to exercise its rights under Section
365(h)(1)(A)(ii) of the Bankruptcy Code to stay in possession of the Subleased
Premises and, effective upon the date that this Sublease becomes a direct lease
between Master and Sublessee pursuant to Section E.w. above, Master Lessor
hereby assumes Sublessor's obligations (expressly excluding any of Sublessor's
obligations set forth in Section E.v. above) under this Sublease to the extent
arising and accruing after the Effective Date.

            bb. Rooftop Communication Equipment. Sublessee shall have the right
to maintain any currently existing rooftop communication equipment, and to
install additional rooftop communication equipment that is utilized for
Sublessee's own use, on the roof of the East Tower in such locations and
pursuant to the Declaration, rules or regulations covering the Subleased
Premises as well as any plans and specifications which are reasonably acceptable
to Sublessor, such approval not to be unreasonably withheld or delayed.

SUBLESSOR AND SUBLESSEE HAVE CAREFULLY READ AND REVIEWED THIS SUBLEASE AND EACH
TERM AND PROVISION CONTAINED HEREIN OR INCORPORATED HEREIN BY REFERENCE AND, BY
EXECUTION OF THIS SUBLEASE, SHOW THEIR INFORMED AND VOLUNTARY CONSENT THERETO.
THE PARTIES HEREBY AGREE THAT, AT THE TIME THIS SUBLEASE IS EXECUTED, THE TERMS
OF THE SUBLEASE ARE COMMERCIALLY REASONABLE AND EFFECTUATE THE INTENT AND
PURPOSES OF SUBLESSOR AND SUBLESSEE WITH RESPECT TO THE SUBLEASED PREMISES AND
THAT SUBLESSOR AND SUBLESSEE ARE EACH RELYING SOLELY UPON THE ADVICE OF THEIR
OWN LEGAL COUNSEL AS TO THE LEGAL AND TAX CONSEQUENCES HEREOF.

                                      LEASE

      THIS EAST TOWER LEASE (this "LEASE") is entered into as of March 24, 2005,
to be effective as of the Closing Date pursuant to the Purchase Agreement (as
such initially capitalized terms are defined in Recital B below) (the "EFFECTIVE
DATE") by and between IDF/KBS 4000 MacArthur, LLC, a Delaware limited liability
company ("LANDLORD") and Conexant Systems, Inc., a Delaware corporation
("TENANT").

                                    RECITALS

      A. Landlord is the owner of that certain real property (the "PROPERTY")
located in the City of Newport Beach, County of Orange, State of California,
commonly known as 4000 MacArthur Boulevard, as legally described on Exhibit A
attached hereto, together with all existing and hereafter constructed
improvements thereto, including, but not limited to, two (2) buildings connected
by a two-story bridge totaling approximately 373,447 rentable square feet -- one
building commonly referred to as the "East Tower" with the two-story bridge
(collectively, the "EAST TOWER") contains approximately 193,137 rentable square
feet and the other, referred to as the "West Tower" (the "WEST TOWER"), contains
approximately 180,310 rentable square feet (collectively, the "IMPROVEMENTS"),
and all of Landlord's right, title and interest in and to all rights,
privileges, easements and appurtenances benefiting the Property (collectively,
the "APPURTENANT RIGHTS"). The Property, the Improvements and the Appurtenant
Rights are collectively referred to herein as the "PROJECT." The West Tower is
located on the west side of the Property and the East Tower is located on the
east side of the Property.

      B. Approximately concurrently with the execution and delivery of this
Lease, Tenant, as Seller, and Landlord, as Buyer, are entering into that certain
Purchase and Sale Agreement and Joint Escrow Instructions (the "PURCHASE
AGREEMENT") providing for the sale of the Project to Landlord. This Lease shall
be effective at 12:01 a.m. on the "Closing Date" as defined in the Purchase
Agreement (herein, the "CLOSING DATE"). Effective as of the Closing Date,
Landlord desires to lease to Tenant, and Tenant desires to lease from Landlord,
the portion of the Project consisting of the entire East Tower (collectively,
with the Appurtenant Rights benefiting such Improvements, the "PREMISES") on the
terms and conditions set forth below. Landlord acknowledges that, concurrently
with the execution of this Lease, Tenant intends to sublease the entire Premises
to Mindspeed Technologies, Inc., a Delaware corporation ("MINDSPEED") in
accordance with the terms and conditions of an Amended and Restated Sublease
(the "SUBLEASE") between Tenant and Mindspeed. Notwithstanding the foregoing, if
at any time after the Effective Date, Tenant is leasing less than the entire
East Tower under this Lease, then all references in this Lease to the "Premises"
shall mean that portion of East Tower (together with the Appurtenant Rights
benefiting the East Tower) then leased by Tenant under this Lease.

                                   ARTICLE 1
                                    PREMISES

      1.1 LEASE. Effective as of the Closing Date, Landlord hereby leases to
Tenant and Tenant hereby leases from Landlord the Premises for the Term (as
defined in Article 2) and upon

<PAGE>

the terms, covenants and conditions set forth in this Lease. In the event that
the Closing Date fails to occur and the Purchase Agreement terminates for any
reason, this Lease shall be of no further force or effect. From and after the
commencement of the Renewal Term (as defined in Section 2.2) for less than the
entire East Tower, it is acknowledged and agreed that the term Premises shall
not include any Common Areas (as defined in Section 4.8(c)(i) below), and Tenant
shall surrender any such Common Areas to Landlord.

                                    ARTICLE 2
                           TERM AND EXTENSION OPTIONS

      2.1 TERM. This Lease shall be effective from and after, and the term of
this Lease (as may be extended, the "TERM") shall commence on, the Closing Date
(the "COMMENCEMENT DATE") and the Term shall end, subject to Section 2.2 below,
at 11:59 p.m., Pacific time, on June 26, 2008 (the "EXPIRATION DATE").

      2.2 EXTENSION OF TERM.

            (a) Provided that no Event of Default has occurred and is continuing
as of (i) the date Tenant gives notice to Landlord hereunder of its election to
extend the Term, or (ii) the Expiration Date, Tenant shall have the right to
extend the Term for all or a portion of the Premises (the "RENEWAL OPTION") for
one (1) two (2) year period (the "RENEWAL TERM"); provided, however,
notwithstanding the foregoing, (x) the portion of the Premises for which Tenant
elects to exercise its Renewal Option must (i) consist of one or more full
floors, with each floor being occupied by either Tenant, Mindspeed under the
Sublease or both Tenant and Mindspeed under the Sublease, and (ii) start on the
first floor (the "FIRST FLOOR") of the East Tower, and (y) Tenant shall be
required to exercise the Renewal Option for all floors, if any, situated between
the First Floor and the highest floor in the East Tower in which Tenant solely
or Tenant and Mindspeed under the Sublease (and not Mindspeed solely) occupies
space (the "TOP FLOOR") and for which Tenant elects to exercise the Renewal
Option; provided, further, however, that it is expressly acknowledged and agreed
that Tenant may exercise the Renewal Option for full floors above the Top Floor
that are occupied solely by Mindspeed under the Sublease. On the first day of
the Renewal Term, Tenant shall make the lump sum payment, if any, required to be
made under Section 2.2(e) below and/or shall execute and deliver to Landlord the
Renewal Term Capital Expense Acknowledgement (as such term is defined in Section
2.2(e) below), if any, required to be executed under Section 2.2(e) below. The
Renewal Option granted to Tenant herein is not personal to Tenant and may be
exercised by any permitted assignee under the terms of this Lease or by any
subtenant to which such right is specifically granted. Any such extension of the
Term shall be subject to and on all of the same terms and conditions of this
Lease, as the same may be amended, supplemented or modified from time to time,
except that Monthly Rental shall be equal to the Monthly Rental payable during
the last year of the initial Term subject to adjustment pursuant to Section 4.2
below. Without in any way limiting the foregoing, there shall be no increase in
the Security Deposit, parking charges, insurance requirements or any other
matters bearing on the economics contained in this Lease other than the Monthly
Rental. At least twelve (12) months prior to the Expiration Date, Tenant shall
provide Landlord with written notice stating that Tenant is exercising its
extension option (the "EXTENSION NOTICE").

            (b) Intentionally Omitted.

<PAGE>

            (c) Intentionally Omitted.

            (d) Intentionally Omitted.

            (e) Tenant covenants and agrees that, if Tenant exercises the
Renewal Option, Tenant shall, on or before the first day of the Renewal Term,
(1) to the extent Tenant has exercised the Renewal Option for the entire East
Tower, make a lump sum payment to Landlord equal to the sum of all Applicable
Adjusted Uncovered Capital Expense Balances (as defined below in this Section
2.2(e)), if any, for all Capital Expense items completed or put in service
through the last day of the current Term of this Lease, and (2) to the extent
Tenant has exercised the Renewal Option for only a portion of the East Tower,
acknowledge in writing ("RENEWAL TERM CAPITAL EXPENSE ACKNOWLEDGMENT") to
Landlord, the aggregate amount, as of the Expiration Date, of all Applicable
Adjusted Uncovered Capital Expense Balances, if any, for all Capital Expense
items completed or put in service through the last day of the initial Term of
this Lease.

            For purposes of this Lease, the following terms shall have the
following meanings:

            (i) the term "ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE" shall mean
at any time and from time to time with respect to any Uncovered Capital Expense
Balance (as such term is defined in Section 8.1(c)(ii) below) required to be
paid by Landlord under Section 8.1(c)(ii) below, the original amount of such
Uncovered Capital Expense Balance, less any portion of such Uncovered Capital
Expense Balance for which Landlord receives reimbursement from Tenant from time
to time under this Section 2.2(e) and/or under Section 4.8(d)(i) below as a
result of Tenant's exercise of the Renewal Term, less any portion of such
Uncovered Capital Expense Balance that has become a Lost Uncovered Expense
Balance (as such term is defined below in this Section 2.2(e));

            (ii) the term "APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE
BALANCES" shall mean at any time and from time to time an amount determined by
adding together the Applicable Adjusted Uncovered Capital Expense Balance for
all Capital Expense items paid by Landlord under Section 8.1(c) below from time
to time;

            (iii) the term "APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE
BALANCE" shall mean at any time and from time to time, as to any Adjusted
Uncovered Capital Expense Balance, an amount determined by multiplying such
Adjusted Uncovered Capital Expense Balance by a fraction, the numerator of which
is x and the denominator of which is y, where

                  (A) x equals the lesser of (1) the Useful Life (as such term
is defined in Section 8.1(c)(i) below) of the Capital Expense item that gave
rise to such Adjusted Uncovered Capital Expense Balance, minus the number of
years (or any portion thereof) that have expired since the Capital Expense item
that gave rise to such Uncovered Capital Expense Balance was completed or put in
service at the East Tower (hereinafter referred to as the "REMAINING USEFUL
LIFE") or (2) the Renewal Term, "New Lease Option Term" or "New Lease Renewal
Term" (as such terms are defined in Section 2.3 below), as applicable, and

<PAGE>

                  (B) y equals the Remaining Useful Life of the Capital Expense
that gave rise to the Uncovered Capital Expense Balance under Section 8.1(c)
below;

            (iv) the term "LOST UNCOVERED EXPENSE BALANCE" shall mean, at any
time the Adjusted Uncovered Capital Expense Balance is being calculated for the
Renewal Term, New Lease Option Term or New Lease Renewal Term, an amount
determined by multiplying (a) 1, minus Tenant's Portion, by (b) the Adjusted
Uncovered Capital Expense Balance existing immediately prior to calculating the
Lost Uncovered Expense Balance;

            (v) the term "LOST UNCOVERED EXPENSE BALANCES" shall mean, at any
time the Adjusted Uncovered Capital Expense Balance is being calculated for any
Renewal Term, the New Lease Option Term or the New Lease Renewal Term, an amount
determined by adding together each Lost Uncovered Expense Balance previously
calculated in connection with the determination of the Adjusted Uncovered
Capital Expense Balance; and

            (vi) the term "TENANT'S PORTION" shall mean at any time, and from
time to time, the quotient determined by dividing the rentable square footage of
the Premises for the Renewal Term, the New Lease Option Term or the New Lease
Renewal Term, as applicable, by the rentable square footage of the Premises for
the Term immediately preceding the Renewal Term, the New Lease Option Term or
the New Lease Renewal Term, as applicable.

Attached hereto as Exhibit E and made a part hereof are examples of how to
calculate the Applicable Adjusted Uncovered Capital Expense Balance for any
Capital Expense item.

      2.3 NEW LEASE OPTION AND NEW LEASE RENEWAL OPTION

                  (a) (i) Tenant shall have the right, exercisable by delivery
of written notice to Landlord ( the "NEW LEASE NOTICE") no less than twelve (12)
months prior to the expiration date of the Renewal Term, to enter into a new
lease for all or a portion of the Premises (the "NEW LEASE OPTION") for a period
commencing on the day following the expiration of the Renewal Term and ending on
the last day of the initial Term (as such term is defined in the Other Lease, as
defined in Section 2.3(b)(i) below) of the Other Lease (hereinafter referred to
as the "NEW LEASE OPTION TERM") subject to each of the following conditions: (A)
no Event of Default has occurred and is continuing as of (1) the date Tenant
delivers the New Lease Notice to Landlord, or (2) as of the last day of the
Renewal Term, (B) as of the first day of the New Lease Option Term, the Other
Lease (as such term is defined in Section 4.8(a)(i) below) remains in effect and
no Event of Default (as such term is defined in the Other Lease) has occurred
and is continuing under the Other Lease, and (C) Tenant has exercised the
Renewal Option in accordance with the provisions of Section 2.2(a) above and, as
of the last day of the Renewal Term, this Lease remains in full force and
effect; provided, however, notwithstanding the foregoing, the portion of the
Premises for which Tenant elects to exercise its New Lease Option (x) can only
be exercised with respect to all or a portion of the Premises then being leased
at the end of the Renewal Term, and (y) must start on the first floor of the
East Tower and continue on contiguous full floors above the first floor so that,
taken as a whole, all of the Premises that are the subject of such New Lease
Option are contiguous full floors starting on the first floor of the East Tower
and ending on the highest full floor comprising the Premises that is the subject
of the New Lease Option.

<PAGE>

                  (ii) The New Lease Option granted to Tenant herein is personal
to Tenant and may not be exercised by any assignee under the terms of this
Lease, other than an assignee permitted under clauses (a), (x), (y) or (z)
appearing in Section 10.1 below. The lease of space in the East Tower pursuant
to the exercise of the New Lease Option shall be documented through the
execution and delivery by Landlord and Tenant of a new lease (the "NEW LEASE")
prior to the expiration of the Renewal Term that shall be substantially in the
form of this Lease, except that the New Lease will differ from this Lease in the
manner described in Exhibit D attached hereto. Monthly Rental under the New
Lease shall be equal to the product of (a) the rentable square footage of the
Premises being leased under the New Lease, with such rentable square footage
being determined based upon the measurements set forth in Exhibit B attached
hereto, multiplied by (b) the monthly rental rate per rentable square foot
payable under the Other Lease for the period during which the New Lease will be
in effect.

                  (iii) Tenant covenants and agrees that, if Tenant exercises
the New Lease Option, Tenant shall, on or before the first day of the New Lease
Option Term, (i) to the extent Tenant has exercised the New Lease Option for the
entire East Tower, make a lump sum payment to Landlord equal to the sum of all
Applicable Adjusted Uncovered Capital Expense Balances, if any, for all Capital
Expense items completed or put in service under this Lease prior to the
commencement of the New Lease Option Term, or (ii) to the extent Tenant has
exercised the New Lease Option for only a portion of the East Tower, acknowledge
in writing ("NEW LEASE CAPITAL EXPENSE ACKNOWLEDGMENT") to Landlord the
aggregate amount of (with respect to the Premises to be leased under the New
Lease and the Remaining Useful Life of the Capital Expense item(s)) all
Applicable Adjusted Uncovered Capital Expense Balances, if any, for all Capital
Expense items completed or put in service prior to the commencement of the New
Lease Option Term, which New Lease Capital Expense Acknowledgment shall also set
forth the dollar amount of the monthly payments to be made by Tenant during the
New Lease Term as Building Operating Costs in payment of the amount set forth in
the New Lease Capital Expense Acknowledgment; the amount of such monthly
payments and/or lump sum payments shall be set forth in the New Lease. The
monthly amount to be paid during the New Lease Option Term in payment of the
amount set forth in the New Lease Capital Expense Acknowledgment shall be equal
to the product of (1) the amount set forth in the New Lease Capital Expense
Acknowledgment, multiplied by (2) 1/56.75.

            (b) (i) The New Lease shall provide that, so long as no Event of
Default (as such term is defined in the New Lease) has occurred and is
continuing thereunder as of (i) the date Tenant gives notice to Landlord
thereunder of its election to extend the New Lease Option Term, or (ii) the
expiration of the New Lease Option Term, and provided that Tenant has exercised
its renewal option under Section 2.2 of the lease dated of even date herewith
between Landlord and Tenant for the West Tower (the "OTHER LEASE") so that the
Other Lease continues in effect during the New Lease Renewal Term (as such term
is defined below in this Section 2.3(b)), Tenant shall have the right to extend
the New Lease Option Term for all or a portion of the Premises (the "NEW LEASE
RENEWAL OPTION") for one (1) five (5) year period (the "NEW LEASE RENEWAL TERM")
by notice to Landlord delivered within thirty (30) days after the "Fair Market
Rental Rate" (as defined in the Other Lease) is determined under the Other
Lease; provided, however, notwithstanding the foregoing, the portion of the
Premises for which Tenant elects to exercise its New Lease Renewal Option (x)
can only be exercised with respect to all or a portion of the Premises then
being leased at the end of the New Lease Option Term, and (y) must

<PAGE>

start on the first floor of the East Tower and continue on contiguous full
floors above the first floor so that, taken as a whole, all of the Premises that
are the subject of such New Lease Renewal Option are contiguous full floors
starting on the first floor of the East Tower and ending on the highest full
floor comprising the Premises that is the subject of the New Lease Renewal
Option.

                  (ii) The New Lease Renewal Option granted to Tenant under the
New Lease is personal to Tenant and may not be exercised by any permitted
assignee under the terms of the New Lease other than an assignee permitted under
clauses (a), (x), (y) or (z) appearing in Section 10.1 below. Any such extension
of the New Lease Option Term shall be subject to and on all of the same terms
and conditions set forth in the New Lease, as the same may be amended,
supplemented or modified from time to time. Monthly rental under the New Lease
during the New Lease Renewal Term shall be equal to the product of (a) the
rentable square footage of the Premises being leased under the New Lease, with
such rentable square footage being determined based upon measurements set forth
in Exhibit B attached hereto, multiplied by (b) the monthly rental rate per
rentable square foot payable under the Other Lease during the period that the
New Lease Renewal Term will be in effect.

                  (iii) The New Lease shall also provide that, if Tenant
exercises the New Lease Renewal Option, Tenant shall, on or before the first day
of the New Lease Renewal Term, (A) to the extent Tenant has exercised the New
Lease Renewal Option for the entire East Tower, make a lump sum payment to
Landlord equal to the sum of all Adjusted Uncovered Capital Expense Balances, if
any, for all Capital Expense items completed or put in service under this Lease
prior to the commencement of the New Lease Renewal Term, or (B) to the extent
Tenant has exercised the New Lease Renewal Option for only a portion of the East
Tower, acknowledge in writing ("NEW LEASE RENEWAL CAPITAL EXPENSE
ACKNOWLEDGMENT") to Landlord the aggregate amount of (with respect to the
Premises to be leased under the New Lease during the New Lease Renewal Term) all
Applicable Adjusted Uncovered Capital Expense Balances, if any, for all Capital
Expense items completed or put in service prior to the commencement of the New
Lease Renewal Term, which New Lease Renewal Capital Expense Acknowledgment shall
also set forth the dollar amount of the monthly payments to be made by Tenant
during the New Lease Renewal Term as Building Operating Costs in payment of the
amount set forth in the New Lease Renewal Capital Expense Acknowledgment. The
monthly amount to be paid during the New Lease Renewal Term in payment of the
amount set forth in the New Lease Renewal Capital Expense Acknowledgment shall
be equal to the product of (1) the amount set forth in the New Lease Renewal
Capital Expense Acknowledgment, multiplied by (2) 1/60.

                                    ARTICLE 3
                                   POSSESSION

      3.1 CONDITION. Tenant hereby acknowledges that it is currently in
possession of the Premises, and is familiar with the condition thereof and
accepts the Premises in its "AS-IS" condition with all faults, and Landlord
makes no representation or warranty of any kind with respect to the Premises.

<PAGE>

                                    ARTICLE 4
                                     RENTAL

      4.1 MONTHLY RENTAL. Tenant shall pay to Landlord the amount of Three
Hundred Twenty Eight Thousand Three Hundred Thirty Two and 90/100ths Dollars
($328,332.90) ("MONTHLY RENTAL") in advance, on or before the first (1st) day of
each month, without prior demand, commencing on the Commencement Date. Should
the Commencement Date be a day other than the first (1st) day of a calendar
month, then the monthly installment of Monthly Rental for the first partial
month shall be an amount equal to the Monthly Rental times a fraction, the
numerator of which is the actual number of days from and after the Commencement
Date in such partial month and the denominator of which is the actual number of
days in such month. Notwithstanding the foregoing, Monthly Rental for the first
month of the Term (prorated based on the actual number of days in such month if
the Term commences on a day other than the first day of a month) shall be paid
through the escrow established pursuant to the Purchase Agreement. Upon the
commencement of any Renewal Term for less than the entire Premises which were
the subject of this Lease at the time the Renewal Option was exercised, Monthly
Rental shall be revised to the product of (a) the usable square footage of the
Premises (using the calculations set forth in Exhibit B attached hereto and
using a 15.34% load factor) after such commencement, multiplied by (b) the
applicable square foot rate determined in accordance with Section 2.2 above.
Notwithstanding anything stated to the contrary in this Section 4.1 or elsewhere
in this Lease, following Landlord's written request to Tenant given at least
twenty (20) days prior to the date the next installment of Monthly Rental is due
hereunder, Tenant shall promptly request and direct (the "DIRECT PAYMENT
NOTICE") Mindspeed to remit directly to Landlord (in accordance with written
instructions provided by Landlord) all Monthly Rental due and owing by Mindspeed
to Tenant thereafter from time to time under the Sublease and any such Monthly
Rental received by Landlord from Mindspeed under the Sublease shall be credited
against the Monthly Rental due by Tenant under this Lease. In no event shall an
Event of Default have occurred hereunder as a result of Mindspeed's late payment
to Landlord of any installment of Monthly Rental unless and until, within five
(5) business days after Landlord gives Tenant written notice of Mindspeed's
failure to pay an installment of Monthly Rental, Tenant fails to pay the same
within such five (5) business days after such notice is given; provided,
however, in the event Landlord receives from both Mindspeed and Tenant payments
with respect to any installment of Monthly Rental, Landlord shall, within one
(1) business day after receipt of the duplicate payment for such month remit to
Tenant the amount paid by Tenant; and provided, further, that Tenant shall have
the right, at Tenant's cost and upon not less than ten (10) days prior written
notice to Landlord and during Landlord's normal business hours, to audit
Landlord's records with respect to Landlord's receipt of Monthly Rental received
directly from Mindspeed.

      4.2 ADJUSTMENTS TO MONTHLY RENTAL. The Monthly Rental payable under
Section 4.1 shall be increased annually commencing on the first (1st) day of the
calendar month immediately following the first anniversary of the Commencement
Date and on each anniversary of such date thereafter (each an "ADJUSTMENT DATE")
including, without limitation, on the first day of the Renewal Term.
Notwithstanding the foregoing, in no event shall the first day of the New Lease
Option Term or the first day of the New Lease Renewal Term be an Adjustment
Date. Upon the Adjustment Date the Monthly Rental amount shall be increased by
three percent

<PAGE>

(3%) of the Monthly Rental payable by Tenant immediately prior to the applicable
Adjustment Date.

      4.3 ADDITIONAL RENTAL. In addition to Monthly Rental, Tenant shall pay, as
Additional Rental, all sums required to be paid by Tenant pursuant to this Lease
(including, but not limited to, interest, late charges, the Property Management
Fee (as defined in Section 4.8(b) below), Tenant's Share (as defined below) of
Development Operating Expenses, Building Operating Costs (as such terms are
defined in Sections 4.8(a) and 4.8(c) below), Taxes (as defined in Section 5.1
of this Lease) as and when required, utilities, maintenance expenses and
insurance premiums (as and when required by Article 11 of this Lease)). Landlord
shall have the same rights and remedies for the nonpayment of Additional Rental
as it has with respect to the nonpayment of Monthly Rental. "TENANT'S SHARE",
shall mean at any time, and from time to time, (a) as to any item of expense
that is included in Additional Rental payable hereunder and that is incurred by
Landlord or levied against Landlord with respect to the East Tower, a percentage
determined by dividing the rentable square footage of the Premises by the
rentable square footage of the East Tower, and (b) as to any item of expense
that is included in Additional Rental payable hereunder and that is incurred by
Landlord or levied against Landlord with respect to the Project as a whole (and
that is not separately calculated with respect to the East Tower), a percentage
determined by dividing the rentable square footage of the Premises by the
rentable square footage of both the West Tower and the East Tower. Without
limiting the foregoing, Landlord and Tenant acknowledge and agree that Tenant's
Share of Development Operating Expenses, Taxes and insurance will be determined
in accordance with clause (b) above.

      4.4 PAYMENT OF RENT. All rental shall be paid in lawful money of the
United States.

      4.5 PLACE OF PAYMENT. Tenant shall pay Monthly Rental and Additional
Rental to Landlord at c/o PM Realty Group, 4675 MacArthur Court, Suite 470,
Newport Beach, California 92660, Attention: Mike Muller, Accounting, or to such
other address as Landlord may from time to time designate in writing to Tenant.

      4.6 LATE PAYMENTS. If Tenant fails to pay any Monthly Rental or Additional
Rental to Landlord within ten (10) days after the same is due, Tenant shall pay
a late fee of five percent (5%) of the unpaid amount. Tenant acknowledges that
the late payment to Landlord of any installment of Monthly Rental or Additional
Rental will cause Landlord to incur certain costs and expenses, the exact amount
of which are extremely difficult or impractical to determine. These costs and
expenses may include, but are not limited to, administrative and collection
costs and processing and accounting expenses. Therefore, Landlord and Tenant
agree that the aforementioned late fee represents a reasonable estimate of the
costs and expenses Landlord will incur and is fair compensation to Landlord for
its loss suffered by reason of late payment by Tenant to Landlord. All such late
charges and interest shall be deemed Additional Rental.

      4.7 SECURITY DEPOSIT.

            (a) The parties agree that, concurrently with the execution of this
Lease, through the escrow established pursuant to the Purchase Agreement, Tenant
shall deliver to Landlord a security deposit in the amount of Three Hundred
Twenty Eight Thousand Three

<PAGE>

Hundred Thirty Two and 90/100ths Dollars ($328,332.90) (the "SECURITY DEPOSIT"),
which shall be in the form of an irrevocable standby letter of credit in a form
and issued by a financial institution selected by Tenant and reasonably
acceptable to Landlord (the "LETTER OF CREDIT"), as security for the performance
by Tenant of the terms of this Lease to be performed by Tenant and the terms of
the Other Lease(as such term is defined in Section 2.3(b)(i) above) to be
performed by Tenant. Within three (3) business days after commencement of the
Renewal Term, the New Lease Option Term or the New Lease Renewal Term for less
than the Premises which were the subject of this Lease at the time the
applicable option therefor was exercised, Landlord shall cooperate with Tenant
in causing the face amount of the Letter of Credit to be reduced (and/or any
cash portion of the Security Deposit to be appropriately reduced) so that the
total amount of the Security Deposit is equal to a prorata share of the Security
Deposit for the initial Term, in the case of the Renewal Term, and for the New
Lease Option Term, in the case of the New Lease Renewal Term. In no event shall
the Security Deposit or any portion thereof be considered prepaid rent. Landlord
may apply such portion or portions of the Security Deposit as are reasonably
necessary for the following purposes: (i) to remedy any Event of Default by
Tenant in the payment of Monthly Rental, Additional Rental, late charge or
interest on defaulted rent, or any other monetary obligation of Tenant under
this Lease and/or the Other Lease; (ii) to repair damage to the Premises and/or
the premises that are the subject of the Other Lease (the "OTHER PREMISES")
caused by Tenant which Tenant is required to repair hereunder or under the Other
Lease if and when the failure of Tenant to repair is an Event of Default which
is continuing; (iii) to clean, restore and repair the Premises and/or the Other
Premises following surrender to Landlord if not surrendered in the condition
required pursuant to the provisions of this Lease and/or the Other Lease; and
(iv) to remedy any other Event of Default of Tenant hereunder and/or under the
Other Lease which is continuing to the extent permitted by law including,
without limitation, paying in full on Tenant's behalf any sums claimed by
materialmen or contractors of Tenant to be owing to them by Tenant for work done
or improvements made at Tenant's request to the Premises and/or the Other
Premises. In this regard, Tenant hereby waives any restriction on the uses to
which the Security Deposit may be applied as contained in Section 1950.7(c) of
the California Civil Code and/or any successor statute. In the event the
Security Deposit or any portion thereof is so used, Tenant shall cause, promptly
upon receipt of written demand therefor accompanied by a statement containing
the specific Tenant default and reasonable supporting evidence (including
invoices and reasonably detailed statements) of the costs and expenses incurred
by Landlord to cure such Tenant default, the Letter of Credit to be restored so
that the amount that can be drawn thereunder is equal to the face amount of the
Letter of Credit (or, if the Security Deposit is being held in the form of cash,
the amount of the Security Deposit shall be restored). To the extent any portion
of the Security Deposit is held by Landlord in cash, the Security Deposit shall
be invested by Landlord in a separate account in a nationally recognized,
reputable financial institution insured by the FDIC and/or in an "A" rated money
market account. Commencing on the first anniversary of the Commencement Date and
annually thereafter, Landlord shall pay to Tenant the amount, if any, of
interest credited to Landlord on the portion, if any, of the Security Deposit
held by Landlord in cash during the prior calendar year, and shall concurrently
provide to Tenant a bank statement for the account covering such period and
reflecting total interest accrued during such period. The entire Security
Deposit not theretofore applied by Landlord as permitted under this Lease
together with all interest accrued thereon and not paid to Tenant as required
hereunder shall be returned to Tenant within thirty (30) days after the
expiration or earlier termination of the Term. If Landlord transfers the Project

<PAGE>

during the Term, Landlord shall transfer the Letter of Credit (and any cash
portion of the Security Deposit together with interest accrued thereon in
accordance herewith to any subsequent owner) in conformity with the provisions
of Section 1950.7 of the California Civil Code and/or any successor statute and,
if any portion of the Security Deposit is in the form of a Letter of Credit, in
conformity with any transfer requirements imposed by the issuer of the Letter of
Credit, in which event the transferring landlord shall be released from all
liability for the return of the Security Deposit and such interest.

            (b) The Letter of Credit shall be an unconditional, irrevocable and
transferable letter of credit in form and issued by a financial institution
("ISSUER") reasonably satisfactory to Landlord and Tenant, it being acknowledged
and agreed that Comerica Bank shall be an acceptable financial institution for
purposes of this Section 4.7 and a letter of credit in the form of Exhibit C
hereto shall, notwithstanding anything to the contrary in this Section 4.7, be
acceptable. The Letter of Credit shall permit partial draws, and provide that
draws thereunder will be honored upon presentation by Landlord. The Letter of
Credit shall have an expiration period of one (1) year but shall automatically
renew by its terms unless affirmatively cancelled by either Issuer or Tenant, in
which case Issuer must provide Landlord thirty (30) days prior written notice of
such expiration or cancellation. The Letter of Credit shall remain in effect
until thirty (30) days after the Expiration Date. Any amount drawn under the
Letter of Credit and not utilized by Landlord for the purposes permitted by this
Lease shall be held in accordance with this Section 4.7. If Tenant fails to
renew or replace the Letter of Credit as required under this Lease or provide a
cash security deposit as permitted below in this Section 4.7(b) at least thirty
(30) days before the Letter of Credit's stated expiration date, Landlord may
draw upon the entire amount of the Letter of Credit. No fees applicable to the
Letter of Credit shall be charged to Landlord. In the event Landlord draws any
amount under the Letter of Credit, Landlord shall promptly notify Tenant thereof
in writing, which written notice shall contain the following information: (i)
the specific Tenant default and (ii) reasonable supporting evidence (including
invoices and reasonably detailed statements) of the costs and expenses incurred
by Landlord to cure such Tenant default. Without waiving any right Tenant may
have to reasonably dispute any such costs or expenses, Tenant shall, promptly
after receipt of such written notice, restore all such amounts drawn by
Landlord; provided, however, in the event that Tenant's restoration of the
amount of the Letter of Credit as required pursuant to this Section results (or
will result) in Landlord holding any Letter of Credit amount and/or proceeds
therefrom in excess of the amount required to be maintained by Tenant, Landlord
shall, concurrently with Tenant's restoration of the Letter of Credit, refund to
Tenant any such excess amount(s). Notwithstanding anything stated to the
contrary in this Section 4.7, if Tenant is not able from time to time to provide
the Security Deposit in the form of a Letter of Credit on commercially
reasonable terms and at commercially reasonable rates (which determinations
shall be made by Tenant in its reasonable discretion), Tenant may provide the
Security Deposit in the form of cash.

      4.8 COMMON AREAS AND PROJECT MAINTENANCE.

            (a) In addition to Monthly Rental and as part of the Additional
Rental payable hereunder, Tenant shall pay to Landlord Development Operating
Expenses (as defined below) attributable to the Premises as follows:

<PAGE>

                  (i) Tenant agrees to pay directly to the property manager (the
"PROPERTY MANAGER") for Koll Center Newport (the "DEVELOPMENT"), as and when
due, Tenant's Share of all costs of maintenance and repair (including management
and administrative fees), insurance, taxes and utilities attributable to the
Development Common Areas (as hereinafter defined) which are now or hereafter
assessed by the Property Manager against the Project pursuant to the Declaration
and attributable to any period during the Term of this Lease (collectively, the
"DEVELOPMENT OPERATING EXPENSES"); provided, however, from and after
commencement of the Renewal Term, the New Lease Option Term or the New Lease
Renewal Term for less than the entire East Tower, Tenant shall pay Tenant's
Share of Development Operating Expenses to Landlord within thirty (30) days
after demand by Landlord therefor. The Development consists of approximately 11
parcels of real property, various office buildings located thereon (including
the Project) and common areas consisting of common driveways and drive aisles,
parking areas, loading areas, sidewalks, landscaped areas and the like which are
not intended or designated for the exclusive use of any occupant(s) of the
Development (collectively, "DEVELOPMENT COMMON AREAS"), as such Development
Common Areas are more particularly described in that certain Declaration of
Covenants, Conditions and Restrictions of Koll Center Newport recorded July 20,
1973, in Book 10811, Page 643 of the Official Records of Orange County,
California, as the same has been amended and modified (as amended, the
"DECLARATION").

                  (ii) Promptly following the Effective Date, and at such other
time as Tenant shall request Landlord in writing, Landlord will request the
Property Manager to deliver directly to Tenant all reasonably estimated and
actual statements of the Development Operating Expenses and Tenant's Share
thereof as and when the same shall be due under the Declaration; provided,
however, from and after commencement of the Renewal Term, the New Lease Option
Term or the New Lease Renewal Term for less than the entire Premises which were
the subject of this Lease at the time the applicable option was exercised,
Landlord shall forward such statements to Tenant immediately upon Landlord's
receipt thereof from the Property Manager, accompanied by a statement advising
Tenant how Tenant's Share thereof was determined. Following delivery of a
written request to Landlord by Tenant, Landlord shall exercise (at Tenant's sole
cost and expense) all rights Landlord may have under the Declaration and at law
or in equity to pursue a protest ("PROTEST") with respect to the amount of
Development Operating Expenses imposed against the Project from time to time
after the Effective Date. To the extent Landlord desires, or Tenant requests
Landlord, to engage a consultant in connection with any such Protest, Landlord
agrees that it shall engage Cyberlease as the consultant or any other consultant
upon which Landlord and Tenant may mutually agree. Notwithstanding the
foregoing, Landlord shall have the right, in lieu of pursuing (or continuing to
pursue if Landlord has already commenced pursuing) any such Protest, to assign
to Tenant (to the extent such right is assignable under the Declaration), either
directly or as Landlord's agent, Landlord's rights under the Declaration to
protest the amount of any Development Operating Expenses hereafter imposed
against the Project from time to time. Tenant covenants and agrees to assign
such rights back to Landlord in writing following completion of any Protest so
pursued by Tenant. Tenant agrees to indemnify, defend, protect and hold Landlord
harmless from and against any and all claims, actions, administrative
proceedings (including informal proceedings), judgments, damages, punitive
damages, penalties, fines, costs, liabilities, interest or losses, including
reasonable attorneys' fees and expenses, consultant fees, and expert fees,
together with all other costs and expenses of any kind or nature, that arise
either as a result of Landlord's pursuing any

<PAGE>

Protest or Tenant's pursuing any Protest as provided above in this Section
4.8(a)(ii); provided, however, notwithstanding the foregoing, (A) Tenant's
indemnity obligations under this Section 4.8(a)(ii) shall not apply to any of
the foregoing to the extent arising out of Landlord's negligence, willful
misconduct or tortious conduct in pursuing any Protest unless the specific
conduct that constitutes such negligence, willful misconduct or tortious conduct
is undertaken by Landlord at Tenant's specific request (in which event Tenant's
Indemnity shall apply), and (B) Tenant's indemnity obligations under this
Section 4.8(a)(ii) shall not apply to the extent that any Protest results in a
determination that additional Development Operating Expenses are owed with
respect to the Project, in which case Landlord and Tenant shall be responsible
for paying their respective shares of the same as provided in this Lease.
Additionally, Landlord agrees to indemnify, defend, protect and hold Tenant
harmless from and against any and all claims, actions, administrative
proceedings (including informal proceedings), judgments, damages, punitive
damages, penalties, fines, costs, liabilities, interest or losses, including
reasonable attorneys' fees and expenses, consultant fees, and expert fees,
together with all other costs and expenses of any kind or nature, that arise as
a result of Landlord's negligence, willful misconduct or tortuous conduct in
pursuing any Protest provided that the indemnity obligations of Landlord under
this Section 4.8(a) shall not apply) to specific conduct constituting the
negligence, willful misconduct or tortious conduct which is undertaken by
Landlord at the specific request of Tenant. Landlord acknowledges that, as of
the Effective Date, Tenant and the Property Manager are engaged in a dispute
(the "EXISTING DISPUTE") regarding the computation of Development Operating
Costs under the Declaration for calendar years 2000 through 2004. Landlord
acknowledges and agrees that Tenant retains all rights it may have with respect
to the Existing Dispute and may pursue the Declarant (as such term is defined in
Section 7.3 below) for reimbursement of amounts paid by Tenant under the
Declaration for periods prior to the Effective Date.

      Landlord agrees that, from and after the Effective Date, and so long as
the Premises consist of no less than three (3) full floors of the East Tower,
Landlord will not consent to any amendment to the Declaration without Tenant's
prior written consent, which consent shall not be unreasonably withheld.

            (b) In addition to Monthly Rental and as part of the Additional
Rental payable hereunder, and provided that Landlord's property manager is not
CB Richard Ellis, an entity owned by, which owns or which is under common
control with CB Richard Ellis or a successor in interest, whether by asset or
stock transfer, to any of the foregoing, Tenant shall pay to Landlord, as and
when Monthly Rental is due hereunder, a property management fee (the "PROPERTY
MANAGEMENT FEE") as follows:

                  (i) Until Landlord is obligated (pursuant to the provisions of
Section 8.1(a)) to assume Tenant's maintenance obligations set forth in Section
8.1(a), the amount payable by Tenant under this Section 4.8(b) shall be equal to
one percent (1%) of the Monthly Rental installment payable by Tenant; and

                  (ii) At any time (if any) that the Premises consist, in the
aggregate, of less than the entire East Tower (in which event, pursuant to
Section 8.1(a), Landlord is obligated to undertake Tenant's maintenance
obligations pursuant to Section 8.1(a)), the amount payable by Tenant under this
Section 4.8(b) shall be equal to that percentage of the Monthly Rental and

<PAGE>

Qualified Additional Rental (as defined below in this Section 4.8(b)(ii))
installment payable by Landlord to its property manager under Landlord's
contract with its property manager and by other tenants of the Project to
Landlord as a property management fee, not to exceed the lesser of (A) that
percentage which is customarily payable in arms-length transactions to property
managers of comparable status and reputation as Landlord's property manager, by
comparable landlords of Comparable Buildings which are multi-tenant in nature,
and Tenant's Share of all costs relating to any property managers, assistant
property managers, administrative personnel and building engineers to the extent
they have responsibilities that are directly attributable to the Premises and
Common Areas (including, without limitation, all onsite costs and depreciation
on new, dedicated equipment) and all costs incurred in establishing, operating,
maintaining and using an onsite office for the Project (only) (including,
without limitation, all depreciation on new dedicated equipment and furniture
and supplies used in an onsite office), but expressly excluding any of such
costs to the extent included in and paid as part of Building Operating Costs (as
such term is defined in Section 4.8(c)(i) below) and (B) three percent (3%). As
used herein, "COMPARABLE BUILDINGS" means Class "A" office buildings in the
Newport Beach/Irvine/John Wayne Airport market area. For the purposes hereof,
"QUALIFIED ADDITIONAL RENTAL" shall mean Additional Rental payable hereunder,
but expressly excluding the following: the Property Management Fee, interest and
late charges, Capital Expenses and Unrelated Alterations.

            (c) In addition to Monthly Rental and as part of the Additional
Rental payable hereunder, Tenant shall pay to Landlord Building Operating Costs
(as defined below) attributable to the Premises as follows:

                  (i) At such time as Landlord is responsible for performance of
the obligations described in Section 8.1(a) below, Tenant shall pay to Landlord
Tenant's Share of "BUILDING OPERATING COSTS", which term as used herein means
the reasonable, out-of-pocket costs and expenses payable by Landlord in
connection with the operation, maintenance and repair of the East Tower and
Common Areas (as defined below), including, but not limited to, (A) the cost of
landscaping, repaving, resurfacing, repairing, replacing, painting, lighting,
cleaning, removing trash, janitorial services, security services, mechanical and
electrical systems and equipment, and other similar items; (B) the total cost of
compensation and benefits of personnel below the level of project manager to
implement the services referenced herein; (C) the cost of operating, repairing
and maintaining life, safety, and access systems, including, without limitation,
sprinkler systems; (D) the cost of water, electricity, gas and any other
utilities provided to the Common Areas; (E) accounting fees and expenses; (F)
municipal inspection fees or charges; and (G) all costs and expenses paid in
leasing air conditioning systems, elevators or other equipment ordinarily
considered to be of a capital nature. The computation of Building Operating
Costs shall be made in accordance with generally accepted accounting principles.
As used herein "COMMON AREAS" means all areas, space, equipment and special
services provided by Landlord for the common or joint use and benefit of the
tenants, their employees, agents, servants, suppliers, customers and other
invitees, including, by way of illustration, but not limitation, restrooms,
stairways, elevators, lobbies and hallways within the East Tower. In no event
shall Building Operating Costs include any of the following:

                        (I) the cost of any work or service performed for any
tenant, including Tenant, at that tenant's cost;

To the extent not previously taken into account in determining Building
Operating Costs, Building Operating Costs shall be reduced by all cash
discounts, trade discounts, or quantity discounts received by Landlord or the
Project manager in the purchase of any goods, utilities, or services in
connection with the operation of the East Tower and/or Project, as applicable.
Landlord shall, to the extent that operating revenues of the Project received by
Landlord are sufficient in amount at the times necessary to make such payments,
attempt to make payments for goods, utilities, and services in a timely manner
to obtain the maximum possible discounts. Landlord shall attempt to make
payments of the type described in the foregoing sentence in the manner described
therein, but shall not be liable to Tenant, nor shall Tenant be entitled to any

<PAGE>

reduction in or offset against Building Operating Costs, in the event Landlord
fails to do so. Landlord will not collect or be entitled to collect Building
Operating Costs from all of its tenants in an amount which is in excess of 100%
of the Building Operating Costs actually paid or incurred by Landlord.

                  (ii) Within ninety (90) days before Landlord first becomes
responsible for performance of the obligations described in Section 8.1(a) below
and at least ninety (90) days before the commencement of each calendar year
thereafter during the Term when Landlord remains responsible for such
obligations, Landlord shall deliver to Tenant a reasonable estimate of the
anticipated Building Operating Costs for the forthcoming calendar year. Tenant
shall pay to Landlord, as Additional Rental, commencing effective as of the date
Landlord first becomes responsible for performance of the obligations described
in Section 8.1(a) below, and continuing on the first day of each calendar month
thereafter while Landlord remains responsible for such obligations, an amount
equal to one-twelfth (1/12th) of the product obtained by multiplying the then
reasonably estimated Building Operating Costs (excluding Capital Expenses for
items considered capital in nature which have not yet been completed or put in
service at the Project) times Tenant's Share.

            (d)  (i) Notwithstanding anything stated to the contrary in this
Section 4.8(d) or elsewhere in this Lease, if Tenant exercises its Renewal
Option, New Lease Option or New Lease Renewal Option for less than the entire
East Tower, then any Applicable Adjusted Uncovered Capital Expense Balance
arising from a Capital Expense item completed or put in service prior to the
commencement of the applicable renewal term shall be considered a Building
Operating Cost and shall be paid on a monthly basis (for the lesser of the
number of months in such ensuing term or the number of months in the Remaining
Useful Life of the applicable Capital Expense item) with all other Building
Operating Costs as follows, instead of being paid in a lump sum as provided in
Section 2.2(e) above: The amount to be paid on a monthly basis (for the lesser
of the number of months in such ensuing term or the number of months in the
Remaining Useful Life of the applicable Capital Expense item) during the ensuing
renewal term shall be equal to the product of (a) such Applicable Adjusted
Uncovered Capital Expense Balance, multiplied by, (b) a fraction, the numerator
of which is 1 and the denominator of which is the lesser of the number of months
(and any portion of any month) in the ensuing renewal term, and the number of
months (and any portion of any month) in the Remaining Useful Life of such
Capital Expense item.

                  (ii) Notwithstanding anything stated to the contrary in this
Section 4.8(d) or elsewhere in this Lease, if Tenant exercises its Renewal
Option, New Lease Option or New Lease Renewal Option for less than the entire
East Tower, then Tenant's Share of any Capital Expense item completed or put in
service after the commencement of the applicable renewal term shall be
considered a Building Operating Cost and shall be paid on a monthly basis (for
the lesser of the number of months remaining in such renewal term or the number
of months in the Remaining Useful Life of the applicable Capital Expense item)
with all other Building Operating Costs as follows, instead of being paid in a
lump sum as provided in Section 8.1(c)(i) below: The amount to be paid on a
monthly basis (for the lesser of the number of months in such renewal term or
the number of months in the Remaining Useful Life of the applicable Capital
Expense item) during the remainder of such renewal term in which the Capital
Expense item was completed or put in service (i.e., during the period of such
renewal term remaining after the date

<PAGE>

such Capital Expense item was completed or put in service) (the "CAPITAL EXPENSE
EFFECTIVE DATE") shall be equal to the product of (a) Tenant's Share of such
Capital Expense item calculated in accordance with the provisions of Section
8.1(c)(i) below, multiplied by (b) a fraction, the numerator of which is 1 and
the denominator of which is the lesser of the number of months (and any portion
of any month) that remain in the applicable renewal term following the Capital
Expense Effective Date and the number of months (and any portion of any month)
in the Remaining Useful Life of such Capital Expense item.

      4.9 ANNUAL STATEMENT; AUDIT RIGHTS.

            (a) The payment of any installment of Tenant's Share of Development
Operating Expenses, Taxes (as defined in Section 5.1(a) below) or insurance
costs incurred by Landlord pursuant to Section 11.2 below or Building Operating
Costs or the Property Management Fee (collectively herein, "OPERATING EXPENSES")
by Tenant shall not preclude it from questioning the correctness of any annual
expense statement in the manner provided in this Section. By no later than
September 15 of each calendar year, Landlord shall deliver to Tenant a statement
of Operating Expenses (an "ANNUAL STATEMENT") incurred with respect to the
Premises for the prior calendar year and the amount previously paid by Tenant
for each category thereof. If the amount of reasonably estimated Operating
Expenses paid by Tenant for any year during the Term exceeds the actual
Operating Expenses for such year, Landlord shall apply any amounts due to Tenant
hereunder to any outstanding amounts due or amounts next coming due from Tenant
to Landlord or, at Tenant's election, deliver such excess to Tenant within
thirty (30) days. If the reasonably estimated Operating Expenses for such year
are less than the actual Operating Expenses for such year, then, subject to the
provisions of Section 4.8(b) above with respect to the Property Management Fee,
Tenant shall pay to Landlord, within thirty (30) days of Tenant's receipt of the
Annual Statement, as additional rent, Tenant's Share of the difference between
the amount of actual Operating Expenses and the amount of reasonably estimated
Operating Expenses. In the event the Term of this Lease expires, or this Lease
is otherwise terminated, Landlord shall compute and prorate the credit or
deficiency up to the date the Lease expired or was terminated and may apply any
credit due Tenant to any outstanding amounts due by Tenant hereunder at that
time and, at the end of the Lease, so long as Tenant is not then in default,
shall refund any excess to Tenant within thirty (30) days after the end of the
Term. Landlord will use reasonable efforts to provide a reasonable estimate of
the Operating Expenses to be set forth in any Annual Statement by no later than
May 31 of each calendar year. If Landlord does not provide to Tenant an Annual
Statement prior to September 15 of the calendar year after the calendar year to
which such Annual Statement applies, Tenant shall have no obligation to pay
Landlord Tenant's Share of any excess of actual Operating Expenses over the
amount of reasonably estimated Operating Expenses paid by Tenant reflected on
such Annual Statement. Notwithstanding anything stated to the contrary herein,
the Annual Statement prepared by Landlord shall only be required to contain a
statement of those categories of Operating Expenses charged to Tenant by
Landlord during the previous calendar year.

            (b) Tenant and its authorized representatives shall have the right,
at Tenant's cost and upon not less than ten (10) days prior written notice to
Landlord and during Landlord's normal business hours, to audit Landlord's
records with respect to Operating Expenses. Any such audit shall be performed at
Landlord's principal accounting offices. To facilitate an audit by Tenant,
Landlord shall keep its books and records applicable to Operating Expenses for
any

<PAGE>

calendar year available to Tenant on a reasonable basis for the longer of (i)
three (3) years following the delivery by Landlord to Tenant of the Annual
Statement for such calendar year and (ii) for an additional ninety (90) day
period following the expiration of the period described in clause (i) above if
Tenant commences an audit within the period described in such clause (i).
Landlord shall keep its books and records for Tenant to audit pursuant to this
provision notwithstanding the termination of this Lease.

            (c) Promptly following the conclusion of any audit by Tenant
pursuant to this Section, Tenant shall furnish to Landlord a copy of any report
or summary and conclusions prepared by Tenant's auditor with respect to any
proposed adjustments to Operating Expenses payable by Tenant hereunder. In the
event that it is determined by such audit that Tenant has overpaid Operating
Expenses for any calendar year(s), such overpayment shall be credited against
the next rent coming due under this Lease after the date of such agreement or
determination or, at Tenant's election and in any event at the end of the Term,
refunded to Tenant within thirty (30) days. The costs and fees incurred by
Tenant in conducting such audit (including all costs of photocopying of any
records of Landlord) shall be borne by Tenant. However, in the event that it is
determined as a result of such audit that Tenant has overpaid Operating Expenses
for any calendar year(s) by three percent (3%) or more, Landlord shall reimburse
to Tenant the actual costs incurred by Tenant in conducting such audit. Such
reimbursement shall be made within thirty (30) days after Landlord's receipt of
documentary evidence as to the amount of such costs.

                                    ARTICLE 5
                                      TAXES

      5.1 REAL PROPERTY TAXES.

            (a) As used in this Lease, the term TAXES shall include any form of
tax, assessment (special or otherwise), license fee, license tax, use tax, tax
or excise on rental, or any other levy, charge, expense or imposition imposed by
any federal, state, county or city authority having jurisdiction, or any
political subdivision thereof, or any school, agricultural, lighting, drainage
or other improvement or special assessment district on any interest of Landlord
(including any legal or equitable interest of Landlord or its mortgagee, if any)
in the Project. The term TAXES shall not include Landlord's general income,
inheritance, estate or gift taxes.

            (b) From and after the Commencement Date, Tenant shall pay, prior to
delinquency, Tenant's Share of the Taxes applicable to the Project during the
Term directly to the appropriate taxing authority; provided, however, from and
after commencement of the Renewal Term, New Lease Option Term or New Lease
Renewal Term for less than the entire East Tower, Tenant shall pay Tenant's
Share of Taxes to Landlord as Additional Rent on the later of thirty (30) days
after demand by Landlord therefor or ten (10) days prior to delinquency. Taxes
for any partial year during the Term shall be prorated based on the actual
number of days in the applicable tax year included within the Term. If Tenant is
required to and fails to pay Taxes directly to the taxing authorities, Landlord
may, at its option, pay such unpaid Taxes, along with penalties and interest, if
any, and may collect from Tenant the Taxes, together with penalties and interest
paid by Landlord, as Additional Rental. Tenant shall have the right to contest,
in good faith, any Taxes, provided that Landlord's interests are protected. In
the event

<PAGE>

Landlord receives any refund of Taxes, Landlord shall promptly notify Tenant
thereof. At Tenant's option, Landlord shall (i) credit Tenant's Share of such
tax refund amount(s) against Monthly Rental and/or Additional Rental next coming
due or (ii) refund Tenant's Share of such amount to Tenant by check or wire
transfer in immediately available funds.

      5.2 OTHER PROPERTY TAXES. Tenant shall pay, prior to delinquency, all
taxes, assessments, license fees and public charges levied, assessed or imposed
upon its business operation, trade fixtures, leasehold improvements and other
personal property on the Premises. No taxes, assessments, fees or charges
referred to in this Section 5.2 shall be considered Taxes under the provisions
of Section 5.1.

                                    ARTICLE 6
                                    UTILITIES

      Tenant agrees to pay directly to the appropriate utility company all
charges for utility services supplied to Tenant or the Premises; if the East
Tower is not separately metered from the balance of the Project, Landlord shall,
subject to the limitations set forth below in this Article 6, cause the same to
be so separately metered at Landlord's sole cost and expense. Notwithstanding
anything to the contrary herein, subject to the limitations set forth below in
this Article 6, Tenant may, at Tenant's option, obtain electrical service to the
Premises from a private source. At least six (6) months prior to the expiration
of the Term with respect to any portion of the Premises as a result of Tenant's
election to extend the Term for the Renewal Term, New Lease Option Term or New
Lease Renewal Term for less than the entire East Tower, Landlord shall cause any
portion of the Premises which will not be subject to this Lease during the
applicable renewal term to be separately metered on a floor-by-floor basis,
separate and apart from the Premises which will be subject to this Lease during
such renewal term. Landlord shall not be liable in damages for any failure or
interruption of any utility or service, and no failure or interruption of any
utility or service shall entitle Tenant to terminate this Lease or discontinue
making payments of Monthly Rental or Additional Rental, unless such failure or
interruption is caused by the negligence or intentional misconduct of Landlord.
Notwithstanding anything stated to the contrary above in this Article 6, (a) to
the extent Tenant elects to obtain electrical service for the Premises from a
private source, it must do so at Tenant's sole cost and expense, and (b)
Tenant's obtaining electrical service from a private source is expressly
conditioned upon the same not (i) materially and adversely impairing or
interfering with the operation of the East Tower or the West Tower (it being
acknowledged and agreed that any work by Tenant to accomplish obtaining
electrical service from a private source may involve temporary interruption of
service), or (ii) imposing any material cost or expense on Landlord, including,
without limitation, any cost or expense not borne by Tenant hereunder arising
from the need to separately meter any of the space in the East Tower not being
leased by Tenant. If Tenant fails to pay when due any charges referred to in
this Article 6, Landlord may pay the charge and Tenant shall reimburse Landlord,
as Additional Rental, for any amount so paid by Landlord within ten (10) days
after Tenant's receipt of written demand therefor.

                                   ARTICLE 7
                          TENANT'S CONDUCT OF BUSINESS

      7.1 PERMITTED USE. Tenant may use the Premises, and may permit its
employees, agents and invitees to use the Premises, for any lawful use permitted
by the Declaration including, but not limited to, general office, laboratory,
research and development, assembly, manufacturing, sales, distribution and
warehouse (including, but not limited to, the uses that Tenant is currently
engaged in on the Premises). In no event shall any sublessee of the Premises or
any portion thereof or assignee of Tenant's rights hereunder for whom Landlord's
consent was required under Article 10 below have the right to use the Premises
for any of the following uses without Landlord's prior written consent: (a)
school classroom purposes (other than training sessions and the like for the
occupant's employees), (b) assembly use which would overburden the parking
and/or use of the Development Common Areas, (c) call center, (d) medical clinic
or (e) manufacturing, distribution and warehousing activities.

      7.2 SIGNS. Tenant and any permitted subtenants may affix upon the Premises
any sign, advertising placard, name, insignia, trademark, descriptive material
or other like item (collectively, "SIGNAGE") without Landlord's prior written
approval, provided all such Signage shall be affixed at Tenant's (or the
applicable subtenant's) sole cost and expense and shall be in accordance with,
and permitted by, Applicable Laws (as defined in Section 7.4 below). Tenant
shall maintain (and shall cause all subtenants to maintain) all Signage in good
condition and repair during the Term. Landlord hereby approves of all Signage
existing as of the Commencement Date and agrees that Tenant may replace the
existing Mindspeed Signage with Tenant Signage; provided, however, at such time
(if any) as the Premises consist, in the aggregate, of less than three (3) full
floors of the East Tower, Landlord may, at Landlord's sole cost and expense,
remove (a) Tenant's existing building-top Signage if Landlord has entered into a
lease with a third party who occupies or intends to occupy at least three (3)
full floors of the East Tower which lease grants such third party the right to
comparable East Tower building-top signage, and/or (b) Tenant's existing
monument Signage if Landlord has entered into a lease with a third party who
occupies or intends to occupy at least three (3) full floors of the East Tower
which lease grants such third party the right to comparable East Tower monument
signage. Notwithstanding anything stated to the contrary above in this Section
7.2, if Landlord is responsible for performance of the obligations described in
Section 8.1(a) below, but subject to Tenant's rights hereunder with respect to
building-top signage and monument signage, Landlord may remove all of Tenant's
signage in the Common Areas at Landlord's sole cost and expense, establish
reasonable sign criteria for the Project, remove Tenant's signage from the
monument sign serving the East Tower to add additional names thereon provided
Landlord refabricates Tenant's sign using the existing lettering style with
letters at least as large as the existing letters and installs such refabricated
sign on the monument signage at the top of the monument signage, and may install
a tenant directory in the Common Area lobby of the East Tower, and Tenant shall
be entitled to Tenant's share of such lobby signage.

      7.3 PARKING. Tenant acknowledges and agrees that Tenant shall be entitled
to the use, at its sole cost and expense, of parking spaces available within the
Development Common Areas in accordance with the terms and provisions of the
Declaration and in accordance with any formal and/or informal parking guidelines
("PARKING GUIDELINES") adopted for use of parking within the Development Common
Areas from time to time. Landlord and Tenant acknowledge

<PAGE>

that they have been informed by Ampco (the "PARKING AGENT") (the parking company
that is acting as the agent for the declarant (the "Declarant") under the
Declaration with respect to the use, maintenance and allocation of parking
within the Development Common Areas) that (i) the Parking Guidelines are
intended to limit the number of parking spaces within the Development Common
Areas that may be used by the owners (and their respective tenants) of buildings
within the Development (including, without limitation, the owner of the Project
and its tenants) to 3.15 parking spaces for every 1000 square feet of rentable
square feet (as the same may be modified from time to time, the "PARKING
RATIO"), and (ii) the use of parking spaces within the Development Common Areas
by the owner of the Project and its respective tenants is regulated through the
issuance of parking cards ("PARKING KEY CARDS") by the Parking Agent. In order
to enable both Landlord and Tenant to comply with the Parking Ratio, (1) Tenant
covenants and agrees that if Tenant at any time, and from time to time, requests
or authorizes Parking Key Cards for itself and/or its subtenants (including a
request by Tenant to Landlord to obtain Parking Key Cards for Tenant) which
cause the Parking Ratio to be exceeded for the Premises based upon the rentable
square feet comprising the Premises, then, upon written request by Landlord,
Declarant, Property Manager, Parking Agent or any other party authorized to
enforce the Parking Ratio, Tenant shall obtain the return of Parking Key Cards
necessary to cause the Parking Ratio not to be exceeded as to the Premises, and
(2) Landlord covenants and agrees that, with respect to any portion of the
Project not leased to Tenant from time to time ("LANDLORD SPACE"), if Landlord
at any time, and from time to time, requests or authorizes an aggregate number
of Parking Key Cards for such Landlord Space which cause the Parking Ratio to be
exceeded for the Landlord Space based upon the rentable square feet comprising
the Landlord Space, then, upon written request by Tenant, Declarant, Property
Manager, Parking Agent or any other party authorized to enforce the Parking
Ratio, Landlord shall obtain the return of Parking Key Cards necessary to cause
the Parking Ratio not to be exceeded as to the Landlord's Space. Landlord and
Tenant acknowledge and agree that although it shall generally be their goal not
to request or authorize Parking Key Cards that, when issued, cause the Parking
Ratio as to the Premises and/or the Landlord's Space to be exceeded, their
requesting or authorizing the same shall not constitute a default under this
Lease provided they comply with their respective obligations under clauses (1)
and (2) above in this Section 7.3. Notwithstanding anything to the contrary in
this Section 7.3 or elsewhere in this Lease, but subject to the last sentence of
this Section 7.3, Tenant acknowledges that (a) Landlord's rights with respect to
parking are as set forth in the Declaration and the Parking Guidelines, and
that, pursuant to the Declaration, Landlord does not control specific parking
spaces or any specific number of spaces, (b) Landlord's obligations with respect
to parking hereunder are therefore necessarily limited to providing to Tenant
parking pursuant to, and Landlord's exercise of, its rights with respect to
parking and the Project pursuant to the Declaration and (c) Landlord has not
made any representation or warranty concerning the location or number of parking
spaces that may be made available to Tenant within the Development Common Areas.
Unless required to do so by Declarant or any a third party with enforcement
rights under the Declaration, Landlord shall not require Tenant to surrender any
reserved parking existing as of the Effective Date, or to remove therefrom any
designation of such parking as reserved. Notwithstanding the foregoing, Tenant
shall have the right to pay directly to the Parking Agent the fees charged by
the Parking Agent for its Parking Key Cards or, at Tenant's option, require
Landlord to obtain Parking Key Cards for Tenant, in which case Tenant shall pay
to Landlord as Additional Rental, monthly in advance, the cost of Tenant's
Parking Key Cards charged Landlord by the Parking Agent;

<PAGE>

provided, however, notwithstanding the foregoing, in no event shall Landlord
charge Tenant any more than Landlord is charged by the Parking Agent for Parking
Key Cards and/or for parking.

      7.4 COMPLIANCE WITH LAWS.

            (a) Tenant shall, at its sole cost and expense, after receipt of
written demand from the applicable governmental authorities having jurisdiction
over the Premises, perform (or cause to be performed) all structural and
non-structural repairs, replacements, alterations and improvements to the
Premises necessary to comply with the Declaration and all federal, state and
local laws, statutes, ordinances, building codes, rules and regulations
applicable to the Premises (collectively with the Declaration, "APPLICABLE
LAWS") if, as, when and to the extent that compliance therewith is triggered by
(1) Tenant's particular use of the Premises (as opposed to use as office,
research and development, assembly, manufacturing, sales, distribution,
warehouse and lab space) after the Commencement Date, and/or (2) Alterations (as
defined below) made to the Premises by or on behalf of Tenant after the
Commencement Date; provided, however, that notwithstanding the foregoing or
anything to the contrary in this Lease:

                  (i) Tenant shall not be liable for any costs or expenses
incurred in connection with any earthquake retrofitting of the Project; and

                  (ii) if, and to the extent that, in connection with any
Alterations, Tenant is required by an applicable governmental authority to
perform Alterations, or to perform remedial action with respect to Hazardous
Materials, which are not directly related to the Alterations Tenant desires to
perform (e.g., to cause areas of the Premises other than those which are the
subject of the Alterations to comply with Applicable Laws) (the "UNRELATED
ALTERATIONS"), then Landlord shall be responsible to Tenant for one-half (1/2)
of the cost of the Unrelated Alterations incurred during the initial Term (and
only during the initial Term); provided, however, Landlord's share of such cost
pursuant to this Lease shall not exceed, during each twelve (12) month period
commencing on the Commencement Date and ending on the day immediately preceding
each anniversary of the Commencement Date during the initial Term, Fifty
Thousand Dollars ($50,000) in the aggregate. For example, and without in any way
limiting the foregoing, if Tenant is required by the applicable governmental
authorities to spend an additional ten percent (10%) of the costs of proposed
Alterations to cause elements of the Premises which are not within the scope of
the proposed Alterations to comply with Applicable Laws, or if Tenant is
required in connection with Alterations to cause other elements of the Premises
which are Unrelated Alterations to comply with Applicable Laws due to repeated
improvements to the Premises by Tenant prior to or during the Term of this
Lease, then the cost thereof shall be shared by Landlord as aforesaid.

      Landlord shall pay to Tenant any amount (which shall include third party
costs and reasonable internal costs of Tenant that constitute Unrelated
Alterations to the extent directly attributable to the costs constituting
Unrelated Alterations) for which Landlord is responsible pursuant to this
subsection (a) within ten (10) days of receipt of demand (which demand, in order
to be effective and in order to be considered delivered to Landlord under this
subsection (a), must be accompanied by invoices, vouchers, receipts or other
reasonable documentation evidencing the amounts for which payment is being
requested in such demand) by Tenant and, if

<PAGE>

Landlord fails to do so, the amount due will bear interest at the rate of 6% per
annum from and after the date such costs were incurred until the same are paid
in full.

            (b) Except to the extent of Tenant's responsibility pursuant to
Section 7.4(a), and after receipt of written demand from the applicable
governmental authorities having jurisdiction over the Premises, Landlord shall,
at Landlord's sole cost and expense, without contribution or reimbursement from
Tenant, promptly make all structural and non-structural repairs, replacements,
alterations and improvements to the Project needed to comply with all Applicable
Laws.

            (c) In the event of a damage or destruction and Landlord elects to
or is required to repair, reconstruct or restore the Project pursuant to Article
12 below, Landlord shall, at its sole cost and expense, be responsible for
complying with all Applicable Laws to the extent that the Applicable Laws
require changes or upgrades to the Project and Premises from the condition of
the Project or Premises existing prior to the damage or destruction.

            (d) Except as provided in Section 7.4(a)(ii), Tenant shall have no
obligation under this Section 7.4 with respect to Hazardous Materials or
Hazardous Materials Laws (as each term is defined in Section 7.5 below);
Tenant's other obligations with regard to Hazardous Materials and Hazardous
Materials Laws are set forth in Section 7.5 of this Lease.

            (e) Landlord agrees to indemnify, defend, protect and hold Tenant
harmless from and against any and all claims, actions, administrative

damages, penalties, fines, costs, liabilities, interest or losses, including
reasonable attorneys' fees and expenses, consultant fees, and expert fees,
together with all other costs and expenses of any kind or nature, that arise
from personal injury claims instituted against Tenant by third parties, but only
to the extent such personal injury claims do not arise out of Tenant's
negligence and do arise out of the physical condition of the portion of the East
Tower that, under the terms of Section 8.1 of this Lease, Landlord is obligated
to maintain and keep in repair from time to time. Tenant agrees to indemnify,
defend, protect and hold Landlord harmless from and against any and all claims,
actions, administrative proceedings (including informal proceedings), judgments,
damages, punitive damages, penalties, fines, costs, liabilities, interest or
losses, including reasonable attorneys' fees and expenses, consultant fees, and

Landlord's negligence and do arise out of the physical condition of the portion
of the East Tower that, under the terms of Section 8.1 of this Lease, Tenant is
obligated to maintain and keep in repair from time to time.

their respective agents, employees, contractors, licensees or invitees
(collectively,

<PAGE>

"TENANT AFFILIATES") during the term of this Lease, including any aggravation
caused by Tenant during the Term hereof of a Hazardous Materials condition
existing as of the Effective Date and any remedial work required to be performed
by applicable governmental authorities in connection with Alterations for which
Tenant is responsible under Section 7.4(a) above. Notwithstanding the foregoing,
unless caused by Tenant or Tenant Affiliates during the term of this Lease,
Tenant shall not have any responsibility or liability for any migration of
Hazardous Materials onto the Premises or the Property. Landlord shall reimburse
Tenant for any amounts incurred by Tenant under this Section 7.5 to the extent
Landlord receives insurance proceeds therefor. Tenant's obligations under this
Section 7.5 shall survive the expiration or earlier termination of this Lease
for a period of six (6) months.

            (d) In the event any investigation or monitoring of site conditions
or any clean-up, containment, restoration, removal or other remedial work
(collectively, the "REMEDIAL WORK") is required under any Hazardous Materials
Laws or by any judicial order, or by any governmental entity as the result of
operations or activities upon, or any use or occupancy of any portion of the
Premises, by Tenant or Tenant Affiliates during the Term of this Lease or within
the applicable period specified in the last sentence of subsection (c) above,
Tenant shall perform or cause to be performed the Remedial Work in compliance
with such laws or order. All Remedial Work shall be performed by one or more
contractors selected by Tenant and reasonably approved in advance in writing by
Landlord. All costs and expenses of such Remedial Work shall be paid by Tenant.

                      MAINTENANCE, REPAIRS AND ALTERATIONS

      8.1   MAINTENANCE OBLIGATIONS.

            (a) Subject to subsection (c) below, Tenant, at its sole cost and
expense, shall perform and make all non-structural maintenance, repairs and
replacements to keep the Premises in a condition similar to the Comparable
Buildings (the "REQUIRED CONDITION"), normal wear and tear, casualty and
condemnation excepted, except if and to the extent that (i) such maintenance or
repairs are required by Applicable Laws and Tenant is not responsible therefor
pursuant to Section 7.4(a) above and/or (ii) subject to the provisions of
Sections 8.1(c) and 8.1(d) below, the costs and expenses incurred or to be paid
for such maintenance or repairs are considered capital in nature under generally
accepted accounting principles consistently applied or otherwise; provided,
however, if at any time the Premises consist, in the aggregate, of less than the
entire East Tower, Landlord shall perform the foregoing obligations pursuant to
Section 8.1(b) below; provided, further, however, if at any time after the
responsibility for performance of the obligations described in this subsection
(a) shifts to Landlord the Premises consist, in the aggregate, of the entire
East Tower, then by notice to Landlord Tenant may elect to resume performance of
its obligations pursuant to this subsection (a), in which case Landlord shall
automatically be relieved of its obligations under this subsection (a). Tenant's
obligations under this Section 8.1(a) shall include obtaining and maintaining in
place maintenance service agreements for building systems. Landlord acknowledges
that the Premises are in the Required Condition as of the Effective Date.
Notwithstanding anything stated to the contrary in this Section 8.1(a) or
elsewhere in this Lease, during the last three (3) years of the initial Term of
this Lease (and during the entire Renewal Term under this Lease and the last
three (3) years of the

<PAGE>

New Lease Option Term or New Lease Renewal Term), Tenant shall not, without
Landlord's prior written approval (which approval shall not be unreasonably
withheld or delayed), perform or undertake any maintenance, repairs and/or
replacements with respect to the Premises if, and to the extent, such project
could reasonably be expected to generate a Capital Expense under this Lease
that, when added to Capital Expenses incurred in connection with other (if any)
maintenance, repair, and/or replacement projects undertaken by Tenant during the
then current Lease Year (as such term is defined below in this Section 8.1(a)),
would exceed $50,000 in the aggregate during such current Lease Year. For
purposes of this Lease, "LEASE YEAR" shall mean the twelve (12) month period
commencing on the Effective Date and ending on the one (1) year anniversary of
the Effective Date and each successive twelve (12) month period thereafter.
Landlord acknowledges and agrees that if Tenant requests, and Landlord fails to
grant, Landlord's approval to Tenant's undertaking any such maintenance, repairs
and/or replacements requiring Landlord's approval as provided in this Section
8.1(a), then Tenant's failure to undertake any such maintenance, repairs or
replacements shall not, in and of itself, constitute a default by Tenant under
this Lease.

            (b) Subject to the provisions of Sections 7.4(a) and 8.1(a) above,
and Sections 8.1(c) and 8.1(d) below, (i) if at any time, the Premises consist,
in the aggregate, of less than the entire East Tower, Landlord, at its sole cost
and expense, shall perform and make all non-structural maintenance, repairs and
replacements to keep the Premises and Common Areas in the Required Condition,
normal wear and tear, casualty and condemnation excepted, and (ii) Landlord, at
its sole cost and expense, shall perform and make all structural maintenance,
repairs and replacements to keep the Premises and Common Areas in the Required
Condition, normal wear and tear, casualty and condemnation excepted. All
replacements shall be of a quality equal to or exceeding that of the original.
Landlord shall coordinate with Tenant as to the performance of Landlord's
obligations pursuant to this subsection (b), and shall schedule and perform the
same in such a manner and at such times so as not to interfere with Tenant's
conduct of its business in the Premises.

            (c) All Capital Expenses (as defined in subsection (d) below),
whether paid by Landlord or Tenant (other than Capital Expenses that may be
incurred by Landlord pursuant to Sections 7.4(b) and/or 7.4(c) or that may be
incurred by Tenant pursuant to Section 7.4(a)), shall be amortized over the
"Useful Life" (as defined below) of the item for which the Capital Expenses were
incurred, and such Capital Expenses shall be allocated between Landlord and
Tenant as follows:

                  (i) Tenant shall pay Tenant's Share of that portion of such
Capital Expenses calculated by multiplying the Capital Expense by a fraction,
the numerator of which is the remaining Term of this Lease as of the date the
item which is considered a Capital Expense is completed or put in service at the
East Tower and the denominator of which is the useful life of the item which is
considered a Capital Expense as of the date the item which is considered a
Capital Expense is completed or put in service at the East Tower as determined
in accordance with generally accepted accounting principles (the "USEFUL LIFE");
and

                  (ii) Landlord shall pay the balance of such Capital Expenses
not required to be paid by Tenant pursuant to the immediately preceding clause
(i) (hereinafter referred to as the "UNCOVERED CAPITAL EXPENSE BALANCE").

<PAGE>

            (d) All costs and expenses including any insurance deductible
related thereto if the expense is incurred due to a casualty, incurred or to be
paid for those items at the East Tower which are non-structural and are
considered capital repairs, replacements, improvements or equipment under
generally accepted accounting principles consistently applied, shall be defined
as "CAPITAL EXPENSES," and shall be paid by Landlord and Tenant as follows:

                  (i) Landlord shall pay its portion (as determined pursuant to
Section 8.1(c) above) of such Capital Expenses incurred by Tenant (which shall
include third party costs and reasonable internal costs of Tenant that
constitute Capital Expenses to the extent directly attributable to the costs
constituting Capital Expenses) within ten (10) days of receipt of demand (which
demand, in order to be effective and in order to be considered delivered to
Landlord under this subsection (d)(i), must be accompanied by invoices,
vouchers, receipts or other reasonable documentation evidencing the amounts for
which payment is being requested in such demand) by Tenant and, if Landlord
fails to do so, the amount due will bear interest at the rate of 6% per annum
from and after the date such costs were incurred until such portion is paid.

                  (ii) Except as expressly provided below in this Section
8.1(d), Tenant shall pay Landlord as Additional Rental Tenant's Share (as
determined pursuant to Section 8.1(c) above) of any such Capital Expenses
incurred by Landlord (which shall include third party costs and reasonable
internal costs of Landlord that constitute Capital Expenses to the extent
directly attributable to the costs constituting Capital Expenses), within ten
(10) days after receipt of demand (which demand, in order to be effective and in
order to be considered delivered to Tenant under this subsection (d)(ii), must
be accompanied by invoices, vouchers, receipts or other reasonable documentation
evidencing the amounts for which payment is being requested in such demand) by
Landlord and if Tenant fails to do so, the amount due will bear interest on the
unpaid balance thereof at six percent (6%) per annum until paid, commencing in
the month after the item which is considered a Capital Expense is completed or
put in service at the East Tower. Any Capital Expenses incurred by Landlord at
any time when Landlord is responsible for the obligations described in Section
8.1(a) above shall be reasonably estimated (to the extent capable of being
estimated) by Landlord in advance and disclosed to Tenant in writing. Any
Capital Expenses incurred by Tenant at any time when Tenant is responsible for
the obligations described in Section 8.1(a) above shall be reasonably estimated
(to the extent capable of being estimated) by Tenant in advance and disclosed to
Landlord in writing.

Notwithstanding anything stated to the contrary in this Section 8.1(d),
following the expiration of the initial Term, and at such time that Landlord is
responsible for performance of the obligations described in Section 8.1(a)
above, Capital Expenses shall not be paid by Tenant in a lump sum payment as
provided in this subsection, but shall instead be paid as part of Building
Operating Expenses in accordance with the provisions of Section 4.8(d)(ii)
above.

      8.2 RIGHT TO PERFORM. Subject to Section 8.1(b) above, Landlord shall have
the right to perform any work that Landlord reasonably deems necessary to
prevent waste or deterioration in connection with the Premises. If Landlord
makes any repairs that Tenant is obligated to make pursuant to the terms of this
Lease, Tenant shall pay the cost, of such repairs (which shall include third
party costs and reasonable internal costs incurred by Landlord to the extent
directly attributable to the performance of any such repairs) to Landlord as
Additional Rental, promptly upon receipt of a bill from Landlord for the same.
Tenant shall have the right

<PAGE>

to perform any work that Landlord is required but fails to perform hereunder in
connection with the Premises should Landlord fail to commence such repairs
within thirty (30) days after receipt of written demand therefor or, after
commencing same, Landlord fails to diligently pursue such repairs to completion
within thirty (30) days after receipt of written demand therefor. If Tenant
makes any repairs that Landlord is obligated to make pursuant to the terms of
this Lease, Landlord shall pay its portion of the costs (which shall include
third party costs and reasonable internal costs incurred by Tenant to the extent
directly attributable to the performance of any such repairs) thereof within ten
(10) days of receipt of demand (which demand, in order to be effective and in
order to be considered delivered to Landlord under this Section 8.2, must be
accompanied by invoices, vouchers, receipts or other reasonable documentation
evidencing the amounts for which payment is being requested in such demand) by
Tenant and, if Landlord fails to do so, the amount due will bear interest at the
rate of 6% per annum from and after the date such costs were incurred until the
same is paid in full.

      8.3 ALTERATIONS. Without first obtaining the written consent of Landlord,
which shall not be unreasonably withheld, conditioned or delayed, Tenant shall
not make or cause to be made to the Premises any addition, renovation,
alteration, reconstruction or change (collectively, "ALTERATIONS") (a) involving
structural changes or additions, or (b) subject to Section 7.2 above, to the
exterior of the East Tower; provided, however, that all Alterations (including,
without limitation, build-out of office or lab space) may be made without
Landlord's consent if any Alterations project costs less than Two Hundred Fifty
Thousand Dollars ($250,000.00) in the aggregate for that particular project; and
provided, further, in no event may Landlord withhold consent to avoid payment of
costs of Unrelated Alterations for which Landlord is responsible pursuant to
Section 7.4(a) above. In any event, any Alterations performed by Tenant shall be
made in accordance with Applicable Laws, and where the cost thereof exceeds
$50,000 in the aggregate (including any Alterations already in progress for
which Tenant has not provided Landlord with notice), Tenant shall notify
Landlord five (5) days prior to constructing any Alterations in order to afford
Landlord the opportunity to post a notice of non-responsibility. If Landlord's
consent is required, then Tenant shall submit to Landlord reasonably detailed
plans and specifications for all proposed Alterations when requesting Landlord's
consent therefor. Tenant shall only be obligated to remove or restore
Alterations made to the Premises by Tenant if Landlord, at the time Landlord
grants its consent therefor, states in writing that they must be removed or
restored upon expiration or earlier termination of this Lease. In no event shall
Tenant be required to remove Unrelated Alterations. Subject to the provisions of
Section 19.16, (a) for Alterations for which Landlord's consent is not required
by the terms of this Lease, Tenant shall not be required to remove or restore
such Alterations, and (b) Tenant may, at its option, remove or restore any
Alterations (including Unrelated Alterations paid for by Tenant) at any time on
or before the expiration or earlier termination of this Lease. The term
"IMPROVEMENTS" as used herein shall include all Alterations.

      8.4 NO LIENS BY TENANT. Tenant shall, at all times during Tenant's
occupancy of the Premises, keep the Premises free from any liens arising out of
any work performed or materials furnished by or at the request of Tenant. If any
such liens are filed, Tenant will, at its sole cost, promptly cause such liens
to be released of record or bonded so that it no longer affects title to the
Premises or the Project.

                                 EMINENT DOMAIN

      9.1 TAKING. The term "TAKING," as used in this Article 9, shall mean an
appropriation or taking under the power of eminent domain by any public or
quasi-public authority or a voluntary sale or conveyance in lieu of condemnation
but under threat of condemnation.

      9.2 TOTAL TAKING. In the event of a Taking of the entire Premises, this
Lease shall terminate and expire as of the date possession is delivered to the
condemning authority and Landlord and Tenant shall each be released from any
liability accruing pursuant to this Lease after the date of such termination,
but Monthly Rental and Additional Rental for the last month of Tenant's
occupancy shall be prorated and Landlord shall refund to Tenant any Monthly
Rental and Additional Rental paid in advance.

      9.3 PARTIAL TAKING. Tenant shall have the right to terminate this Lease
upon giving notice in writing of such election to Landlord within thirty (30)
days after Tenant's receipt of written notice that a portion of the Premises has
been or shall be so taken if, (a) there is a Taking of (1) more than ten percent
(10%) of the Premises and Tenant reasonably determines that such Taking will
have a material adverse impact upon Tenant's business or (2) ten percent (10%)
of the parking area for the Premises and Landlord cannot provide immediate
replacement parking (or assurances thereof to Tenant's reasonable satisfaction)
of a similar nature on adjacent and contiguous land and at no additional cost to
Tenant than that provided for in this Lease, (b) there is a Taking of a portion
of the parking area for the Premises and Tenant reasonably determines that such
Taking will have a material adverse impact upon Tenant's business or (c) because
of the laws then in force, the Premises may not be used for the same use being
made before such Taking, whether or not restored. This Lease shall terminate
effective as of the date Tenant is required to vacate the portion of the
Premises taken.

      9.4 AWARD. The entire award or compensation in any such condemnation
proceeding, whether for a total or partial Taking, or for diminution in the
value of the leasehold or for the fee, shall belong to and be the property of
Landlord; and, in any event, the holder of any mortgage or deed of trust
encumbering the Premises shall have a first priority to the extent of the unpaid
balance of principal and interest on its loan; provided, however, Tenant shall
have the right to recover from Landlord the then-unamortized cost of Alterations
paid for by Tenant and for the value of the leasehold estate taken in such
Taking. Tenant shall be entitled to recover from the condemning authority such
compensation as may be separately awarded by the condemning authority to Tenant
or recoverable from the condemning authority by Tenant in its own right for the
taking of trade fixtures, equipment and other personal property owned by Tenant
and for the expense of removing and relocating its business, for loss of
goodwill and for other damages to its business.

      9.5 CONTINUATION OF LEASE. In the event of a partial Taking, if Tenant
does not elect to terminate this Lease as provided above (or has no right to so
terminate), Landlord agrees, at Landlord's cost and expense as soon as
reasonably possible after the Taking, to restore the Project to a complete unit
of like quality and character as existed prior to the Taking and consistent with
a standard at least comparable to the condition of Comparable Buildings (subject

<PAGE>

to Tenant's reasonable approval), provided that in no event shall Landlord be
required to restore Tenant's personal property, trade fixtures or equipment or
any Alterations made by Tenant after the Commencement Date (other than those for
which Landlord is responsible but which are made by Tenant pursuant to the
provisions of Section 8.2) and, thereafter, Monthly Rental, Additional Rental
and the Security Deposit shall be reduced based on the rentable square footage
remaining as compared to the rentable square footage of the building in which
the Premises or portion thereof are in prior to the Taking. In the event of a
Taking of all or a portion of the parking area, if Tenant has no right to or
does not elect to terminate this Lease as provided above, Monthly Rental shall
be reduced on an equitable basis, taking into account the utility and relative
convenience of the portion of the parking spaces Taken and Landlord's
replacement (or partial replacement, as applicable) thereof.

                            ASSIGNMENT AND SUBLETTING

      10.1 LANDLORD'S CONSENT. Tenant shall not assign or sublet all or any part
of this Lease or Tenant's interest in the Premises (collectively, "ASSIGNMENT"
or "ASSIGN") without first procuring the written consent of Landlord, which
consent shall not be unreasonably withheld, conditioned or delayed.
Notwithstanding the foregoing or any other provision of this Lease, Tenant may,
upon written notice to Landlord, but without obtaining Landlord's consent,
without constituting a default under this Lease, and without triggering any
termination or recapture right, (a) Assign this Lease or sublet the Premises or
a portion thereof to (i) any parent or subsidiary entity of Tenant, (ii) any
person or entity that acquires all or substantially all of Tenant's assets or
stock or of the assets of a division or business unit of Tenant operating in the
Premises or a portion thereof, or (iii) any entity with which Tenant merges,
regardless of whether Tenant is the surviving entity, or (b) hereafter sublease
up to fifty percent (50%) in the aggregate of the rentable square footage of the
Premises (inclusive of any space subleased under the Pre-Approved Subleases),
provided any sublease of Premises shall be in accordance with all requirements
of this Lease, including without limitation Section 7.1 above; provided further,
however, the foregoing shall not prohibit or limit Tenant from subleasing back
space from Mindspeed. In addition, the term "Assignment" or "Assign" shall not
mean, and Landlord's consent shall not be required for, any sale or other
transfer of Tenant's capital stock, including, but not limited to, (x) any sale
by an existing shareholder, (y) any public offering by Tenant, or (z) the sale
or transfer of Tenant's stock to take Tenant private. In any event, at
Landlord's request, any assignee of this Lease shall furnish Landlord with a
written assumption of Tenant's obligations under this Lease; if for any reason
Tenant fails or is unable to deliver a written assumption agreement as required
pursuant to this Section, it shall not be deemed a default under this Lease if
Tenant, within thirty (30) days after receipt of Landlord's written request
therefor, causes such assignee to sign and deliver such an assumption agreement
to Landlord. Landlord hereby consents to (1) Tenant's subleasing to Mindspeed
the East Tower in accordance with the provisions of the New Sublease (as such
term is defined in the Purchase Agreement), and (2) Tenant's entering into a
lease with a bank for the operating of the automatic teller improvements
existing at the East Tower and/or amending the existing lease with Bank of
America (collectively the "PRE-APPROVED SUBLEASES"). In order to preserve
Tenant's first offer rights under Section 1.2 of the Other Lease, Landlord
covenants and agrees that, to the extent it has the opportunity or right to do
so, it shall not, at any time on or before the last day that Tenant can deliver
a New

<PAGE>

Lease Notice, enter into any agreement with a subtenant of Mindspeed's for the
East Tower that permits such subtenant's occupancy of the East Tower after the
Expiration Date.

      10.2 PROCEDURES. Should Tenant desire to enter into an Assignment for
which Landlord's consent is required, Tenant shall request, in writing,
Landlord's consent to the proposed Assignment at least five (5) days before the
intended effective date of the proposed Assignment, which request shall include
the following: (a) a copy of the proposed Assignment agreement and (b) any
information relevant to the proposed Assignment that Landlord may reasonably
request. Within three (3) days after Tenant's request for consent to the
proposed Assignment together with all of the above-required information,
Landlord shall respond in writing by either: (i) consenting to the proposed
Assignment; or (ii) refusing to consent to the proposed Assignment and citing
the specific reasonable reason(s) for such refusal. Landlord's failure to
respond within such three (3) day period shall be deemed Landlord's consent to
such proposed Assignment.

      10.3 NO RELEASE/WAIVER. No Assignment, whether with or without Landlord's
consent, shall relieve Tenant from its obligations under this Lease, unless
agreed to otherwise in writing by Landlord. Landlord's consent to one Assignment
shall not be deemed to be Landlord's consent to any subsequent Assignment to any
other party.

      10.4 EXCESS RENTS. With respect to any sublease other than the
Pre-Approved Subleases, Tenant shall pay to Landlord, within thirty (30) days
after the same is paid to Tenant by the subtenant, and if and only after Tenant
recovers (a) all costs, expenses and concessions incurred or agreed to by Tenant
in procuring the sublease, including without limitation tenant improvement
costs, free rent, moving expenses, lease assumptions, marketing costs, brokerage
commissions, attorneys' fees and the like, and (b) any and all costs incurred by
Tenant with respect to the Premises which are subject to such sublease for any
period of time after Tenant vacates the same until the commencement date of the
sublease, fifty percent (50%) of the rental payable under the sublease in excess
of the aggregate of the rental payable to Landlord hereunder and the costs
incurred by Tenant in maintaining, insuring and repairing the Premises which are
the subject of the sublease, including without limitation Taxes and insurance
costs.

                             INSURANCE AND INDEMNITY

      11.1 TENANT'S INSURANCE. Tenant, at its sole cost and expense, shall
procure, pay for and keep in full force and effect throughout the Term the
following types of insurance, in at least the amounts and in the forms specified
below:

            (a) Commercial general liability insurance with combined single
limit for bodily injury, personal injury, death and property damage liability
coverage in the amount of Five Million Dollars ($5,000,000) per occurrence. All
such liability insurance shall specifically insure the performance by Tenant of
the indemnity agreement as to liability for injury to or death of persons and
injury or damage to property set forth in Section 11.4.

            (b) Workers' compensation coverage as required by law.

<PAGE>

            (c) Insurance covering all of Tenant's trade fixtures, equipment and
other personal property from time to time in, on or about the Premises in an
amount not less than their full replacement value from time to time, providing
protection against any peril included within an ISO "Special Form" insurance
policy.

            (d) At such time as Landlord does not provide insurance covering the
Premises, Tenant shall have the right, upon notice to Landlord, to carry
insurance covering the Premises in an amount not less than their full
replacement value from time to time (adjusted on the anniversary of the renewal
date of Tenant's policy), providing protection against any peril included within
an ISO "Special Form" insurance policy and earthquake and flood and terrorism
insurance and, if Tenant is entitled and elects to do so, Tenant shall have no
responsibility to pay any share of the insurance carried by Landlord pursuant to
Section 11.2(a) below. If Tenant has the right to provide insurance of the type
described in the first sentence of this subsection (d), Tenant's election to do
so shall be made within ten (10) business days after receipt of the quote and
the information described in clauses (i) through (iii) of Section 11.2(a) below.
With respect to any policy year after Tenant makes an election to carry the
insurance described in this subsection (d), within ten (10) business days after
Tenant's request therefor, Landlord shall provide Tenant with a written annual
premium quote obtained by Landlord for the insurance described in this
subsection (d) and, at Tenant's election made within ten (10) business days
after receipt of such quote, Tenant may require Landlord to carry the insurance
described in this subsection (d), in which case Tenant shall pay its share
thereof in accordance with Section 11.2(d) below. If Tenant elects to require
Landlord to carry the insurance described in this subsection (d), the foregoing
process (Landlord obtaining a quote for the ensuing policy year and Tenant's
election to require Landlord to carry such insurance or to carry the same
itself) shall be repeated prior to each policy renewal date such that the
election hereunder by Tenant to require Landlord to carry the insurance or to
carry the same itself shall be an annual election which may be made by Tenant at
least ten (10) business days prior to such policy renewal date. Any proceeds of
any policy obtained by Tenant pursuant to this subsection (d) with respect to
damage to the Premises shall be used for the repair or replacement of the
property damaged or destroyed unless this Lease shall cease and terminate under
the provisions of Article 12.

Notwithstanding the foregoing, Tenant shall be deemed to have satisfied its
obligations under this Section 11.1 so long as Mindspeed is maintaining such
insurance.

      11.2 LANDLORD'S INSURANCE.

            (a) Except as provided in Section 11.1(d) above, Landlord shall be
required to carry insurance of the type described in Section 11.1(d) above.
Landlord shall use commercially reasonable efforts to obtain such insurance at
competitive rates. Within ten (10) business days after the Commencement Date,
and at least thirty (30) days prior the renewal date of Landlord's policy
described herein, Landlord shall provide Tenant with a written annual premium
quote for the insurance carried by Landlord pursuant to this Section 11.2(a),
which quote shall include the following information: (i) the total premium
charged to Landlord for the policy period for all properties covered thereby,
(ii) the amount of such premium allocated to the Premises and the methodology
for such allocation and (iii) a detailed description of the portfolio covered by
such policy. In the event Landlord does not provide insurance covering the
Premises by way of a blanket policy covering all properties owned by Landlord
and/or affiliates of Landlord on a

<PAGE>

portfolio basis and Tenant provides reasonable evidence that property insurance
meeting all the requirements of this Lease can be obtained at a more competitive
rate than the quote obtained by Landlord, Landlord shall procure such property
insurance for the ensuing twelve (12) month period with the insurance carrier
proposed by Tenant. No policy for fire and property damage insurance required to
be maintained by Landlord pursuant to this subsection shall have a deductible
greater than Two Hundred Fifty Thousand Dollars ($250,000.00), unless approved
in writing by Tenant.

            (b) Landlord shall maintain commercial general liability insurance
insuring Landlord (and Landlord's lender as an additional insured) against
liability for personal injury, bodily injury, death and damage to property
occurring in, on or about, or resulting from the use or occupancy of the
Project, or any portion thereof, with combined single limit coverage of at least
Five Million Dollars ($5,000,000) per occurrence. Landlord may carry such
greater coverage as Landlord or Landlord's lender may from time to time
determine is reasonably necessary for the adequate protection of Landlord and
the Project, provided that such limit shall in no event exceed the limit carried
by owners of Comparable Buildings similarly situated and operating under similar
circumstances. No such policy for commercial general liability insurance
required to be maintained by Landlord pursuant to this subsection shall have any
deductible amount, unless approved in writing by Tenant. The policy required to
be carried by Landlord pursuant to this subsection (b) shall name Tenant as an
additional insured with respect to occurrences in or about the Common Areas.

            (c) Landlord may maintain any other commercially reasonable
insurance (including flood, earthquake and terrorism insurance) which in the
reasonable opinion of its insurance broker, advisor or legal counsel is prudent
in carry under the given circumstances.

            (d) With each payment of Monthly Rental, Tenant shall pay Landlord,
as Additional Rental, Tenant's Share of one-twelfth (1/12th) of the insurance
premiums for the upcoming twelve (12) month period for the insurance carried by
Landlord pursuant to subsections (a), (b), and (c) above. Concurrently with its
delivery of the statement of the insurance premiums for the ensuing twelve (12)
month period, Landlord shall furnish Tenant with a copy of the carrier's bill to
Landlord for such ensuing twelve (12) month period, together with copies of
cancelled checks (provided Landlord has obtained the same from the bank) showing
the payments of insurance premiums made by Landlord for the twelve (12) month
period just ended and of the insurance bill covering such period.

      11.3 POLICY FORM. All policies of insurance required herein shall be
issued by insurance companies with general policy holder's rating of not less
than A and a financial rating of not less than Class V, as rated in the most
current available "Best's Key Rating Guide," and which are qualified to do
business in the State of California. All policies required to be carried by
Tenant, except for the workers' compensation coverage, shall name as additional
insureds, Landlord and Landlord's mortgagee(s) or beneficiary(ies) for which
Landlord has provided to Tenant their names and addresses. The policy described
in subsection (d) of Section 11.1 shall also name Landlord and such Landlord's
mortgagee(s) or beneficiary(ies) as loss payees with respect to claims arising
from the Premises. Each party shall deliver to the other executed copies of the
policies of insurance or certificates thereof concurrently with the execution of
this Lease. Thereafter, each party shall deliver executed copies of renewal
policies or certificates to the other

<PAGE>

party within ten (10) days prior to the expiration of the term of each policy.
All policies of insurance delivered to a party must contain a provision that the
company writing the policy will give to the other party ten (10) days prior
written notice of any cancellation or lapse or the effective date of any
reduction in the amounts of insurance. All policies required to be obtained and
maintained by either party herein shall be endorsed to read that such policies
are primary policies and any insurance carried by the other party shall be
noncontributing with such policies.

      11.4 BLANKET POLICIES. Notwithstanding anything to the contrary contained
in this Article 11, a party's obligation to carry insurance may be satisfied by
coverage under a so-called blanket or umbrella policy or policies of insurance;
provided, however, that the coverage afforded the other party will not be
reduced or diminished thereby, the insuring party's insurer shall fairly
allocate the premiums for the properties and/or locations covered by such
blanket policy and, upon the request of the other party, the insuring party
shall provide a written allocation of such premiums and the justifications
therefor to the other party, and, with respect to commercial general liability
insurance, there shall be available under such policy for claims pertaining to
the Premises the minimum dollar amount set forth above and the requirements set
forth in this Lease shall otherwise be satisfied by such blanket or umbrella
policy or policies.

      11.5 INDEMNITY.

            (a) LANDLORD, for the purposes of this Section 11.5(a), shall mean
and include Landlord and Landlord's successors, assigns, shareholders, members,
partners, directors, employees, contractors and agents. Tenant shall defend,
indemnify and hold harmless Landlord from and against any and all claims,
actions, causes of action, demands, rights, damages, costs (including reasonable
attorneys' fees and court costs), liabilities, debts, obligations, judgments,
remedies, benefits, losses and expenses of any kind whatsoever (collectively,
"CLAIMS") which may now or in the future be incurred or suffered by Landlord by
reason of, arising out of or connected with (i) Tenant's negligence or
intentional misconduct, or (ii) any material breach of this Lease by Tenant.
Notwithstanding any of the foregoing to the contrary, Tenant shall not be liable
for, and Tenant's indemnity under this Section 11.5(a) shall not extend to (1)
any damage or injury to the extent and in the proportion that the same is
ultimately determined to be attributable to the negligence or intentional
misconduct of Landlord or (2) any punitive damages. Landlord shall reimburse
Tenant for any amounts incurred by Tenant under this Section 11.5(a) to the
extent Landlord receives insurance proceeds therefor. Tenant's obligations under
this Section 11.5(a) shall survive the expiration or earlier termination of this
Lease for a period of one (1) year. Tenant shall have no obligation under this
Section 11.5(a) with respect to Hazardous Materials or Hazardous Materials Laws;
Tenant's obligations with regard to Hazardous Materials and Hazardous Materials
Laws are set forth in Section 7.5 of this Lease.

            (b) TENANT for the purposes of this Section 11.5(b) shall mean and
include Tenant and Tenant's successors, assigns, directors, shareholders,
members, partners, employees, contractors and agents. Landlord shall defend,
indemnify and hold harmless Tenant from and against any and all Claims which may
now or in the future be incurred or suffered by Tenant by reason of, arising out
of or connected with (i) Landlord's negligence or intentional misconduct, or
(ii) any material breach of this Lease by Landlord. Notwithstanding any of the
foregoing to the contrary, Landlord shall not be liable for, and Landlord's
indemnity under this Section 11.5(b) shall not extend to, (1) any damage or
injury to the extent and in the proportion

<PAGE>

that the same is ultimately determined to be attributable to the negligence or
intentional misconduct of Tenant or (2) any punitive damages. Landlord's
obligations under this Section 11.5(b) shall survive the expiration or earlier
termination of this Lease for a period of one (1) year.

      11.6 WAIVER OF SUBROGATION. Landlord and Tenant each waive any rights each
may have against the other on account of any loss or damage occasioned to
Landlord or Tenant, as the case may be, their respective property, or the
Premises or its contents, arising from any liability, loss, damage or injury
caused by fire or other casualty for which property insurance is carried or
required to be carried pursuant to this Lease and all property insurance
policies obtained by Landlord and Tenant (or Mindspeed under the Sublease)
relating to the Premises shall contain endorsements waiving any right of
subrogation which the insurer may otherwise have against the noninsuring party.
The foregoing release and the foregoing requirement for waivers of subrogation
shall be operative only so long as the same shall neither preclude the obtaining
of such insurance nor diminish, reduce or impair the liability of any insurer.

      11.7 FAILURE TO MAINTAIN INSURANCE. If Tenant refuses or neglects to
secure and maintain insurance policies required to be carried by Tenant
hereunder that comply with the provisions of this Article 11, Landlord may
secure the appropriate insurance policies and Tenant shall pay, upon demand
accompanied by reasonable backup documentation with respect thereto, the cost of
same to Landlord (including interest on such amount at the rate of 6% per annum
from and after the date such cost is incurred and until the same is paid), as
Additional Rental. If Landlord refuses or neglects to secure and maintain
insurance policies required to be carried by Landlord hereunder that comply with
the provisions of this Article 11, Tenant may secure the appropriate insurance
policies and Landlord shall pay, upon demand accompanied by reasonable backup
documentation with respect thereto, the cost of same to Tenant (including
interest on such amount at the rate of 6% per annum from and after the date such
cost is incurred and until the same is paid).

                                   ARTICLE 12
                                     DAMAGE

      12.1 INSURED CASUALTY. In the case of damage by fire or other perils
covered by the insurance specified in Article 11, carried or required to be
carried pursuant to Article 11, provided that neither Landlord nor Tenant
terminates this Lease as provided herein, the party responsible to maintain
property insurance covering casualty to the Premises at the time of the
occurrence shall as soon as possible commence such repair, reconstruction and
restoration of the Premises and shall diligently prosecute the same to
completion consistent with a standard at least comparable to the condition of
Comparable Buildings prior to the occurrence of the casualty, but if Landlord is
the repairing party, Landlord shall not be required to restore Tenant's trade
fixtures, equipment and personal property. Notwithstanding the foregoing, if (a)
the Premises is destroyed to an extent of at least fifty percent (50%) of the
then full replacement cost thereof as of the date of destruction, (b) the
destruction occurs during the last two (2) years of the Term with respect to the
portion of the Premises damaged, or (c) the Premises is damaged by any peril
and, because of the laws then in force, the Premises cannot be restored at
reasonable cost in excess of available insurance proceeds or if restored, cannot
be used for the same use being made thereof before such damage, then Tenant and
Landlord shall each have the right to terminate this

<PAGE>

Lease; Tenant shall also have the right to terminate the Lease if damage of the
type described in (a) through (c) above occurs and the Premises cannot be
restored with only minimal impact on Tenant's business. A party may exercise
this termination right by giving written notice to the other party within thirty
(30) days after the date of such destruction. If this Lease is terminated
pursuant to this Section 12.1, then (i) if Landlord is the insuring party, upon
Landlord's receipt of any insurance proceeds payable by reason of such
destruction, Landlord shall pay to Tenant from such proceeds an amount equal to
the Alterations paid for by Tenant, reduced by the amount which has been
amortized as of the date of such termination and by the amount of proceeds of
any insurance carried by Tenant on such items pursuant to Article 11, if any,
and (ii) if Tenant is the insuring party, upon Tenant's receipt of any insurance
proceeds payable by reason of such destruction, after retaining from such
proceeds an amount equal to the Alterations paid for by Tenant, reduced by the
amount which has been amortized as of the date of such termination and by the
amount of proceeds of any insurance carried by Tenant on such items pursuant to
Article 11, if any, Tenant shall pay to Landlord the balance of such proceeds
for the Premises. If Landlord has elected to terminate this Lease as provided in
this Article due to the fact that the estimated cost to restore the Premises
exceeds the insurance proceeds available, Tenant may, at its election (but shall
not be obligated), offer to provide Landlord with funds to cover such shortfall,
within thirty (30) days after Tenant's receipt of Landlord's termination notice,
in which event Landlord shall complete its repair, reconstruction and
restoration of the Premises pursuant to this Article and this Lease shall remain
in full force and effect. If this Lease is not terminated pursuant to the
provisions of this Section, then during the period of repair, reconstruction or
restoration, Tenant shall be entitled to the abatement of (i) all Monthly Rental
and (ii) to the extent Landlord receives rental loss insurance proceeds
therefor, any Additional Rental.

      12.2 UNINSURED CASUALTY. If the Premises is damaged as a result of any
casualty not covered by the insurance specified in Article 11, then, at
Landlord's option, either (a) within thirty (30) days following the date of such
damage, Landlord may elect to, and shall as soon as possible after such
election, commence repair, reconstruction or restoration of the Project and
diligently prosecute the same to completion consistent with a standard at least
comparable to the condition of Comparable Buildings prior to the occurrence of
the casualty or (b) Landlord may elect within said thirty (30) days not to so
repair, reconstruct or restore the damaged property, in which event this Lease
shall cease and terminate upon the expiration of such thirty (30) day period,
unless Tenant agrees within fifteen (15) days after such election to pay the
cost of the repair, reconstruction or restoration, in which event Landlord shall
be deemed to have elected the option in subpart (a) in this Section 12.2. Tenant
shall also have the right to terminate the Lease if uninsured damage occurs and
the Premises cannot be restored with only minimal impact on Tenant's business
or, so long as the Sublease is in effect, Mindspeed's business, by giving
written notice to Landlord within thirty (30) days after the date of such
destruction. If Landlord elects to repair, reconstruct or restore the Premises
following any casualty described in this Section 12.2, then during the period of
repair, reconstruction or restoration, Tenant shall be entitled to the abatement
of (i) all Monthly Rental and (ii) any Additional Rental.

      12.3 LANDLORD'S FAILURE TO COMPLETE. If Landlord either elects or is
required to repair, reconstruct or restore the Premises pursuant to this Article
12, and Landlord fails to complete such repair, reconstruction or restoration of
the Premises on or before the date (the

<PAGE>

"OUTSIDE REPAIR DATE") that is six (6) months after the date of the damage, then
Tenant shall have the right to immediately terminate this Lease upon written
notice to Landlord.

                                   ARTICLE 13
                               DEFAULTS BY TENANT

      13.1  EVENTS OF DEFAULT. Should Tenant at any time:

            (a) fail to make any payment of Monthly Rental, Additional Rental or
any other charge payable by Tenant pursuant to this Lease for a period of ten
(10) days after receipt of written notice from Landlord to Tenant (provided,
however, any notice shall be in lieu of, and not in addition to, any notice
required under Section 1161 of the Code of Civil Procedure of California or any
similar, superseding statute), or

            (b) fail to perform any other of its obligations herein contained
for more than thirty (30) days after receipt of written notice thereof from
Landlord to Tenant specifying the particulars of the default, or within such
longer period as may be reasonably required to cure such default (provided,
however, any notice shall be in lieu of, and not in addition to, any notice
required under Section 1161 of the Code of Civil Procedure of California or any
similar, superseding statute), or

            (c) make any general assignment for the benefit of creditors, or

            (d) have filed against Tenant a petition to have Tenant adjudged a
bankrupt or a petition for reorganization or arrangement under any law, statute,
ordinance, rule or regulation relating to bankruptcy (unless, in the case of a
petition filed against Tenant, same is dismissed within ninety (90) days), or

            (e) institute any proceedings under the Bankruptcy Code or any
similar or successor statute, code or act, or should an appointed trustee or
receiver take possession of substantially all of Tenant's assets located at the
Premises or of Tenant's interest in this Lease where possession is not restored
to Tenant within thirty (30) days, or

            (f) have all or substantially all of Tenant's assets located at the
Premises or Tenant's interest in this Lease attached or judicially seized where
the seizure is not discharged within ninety (90) days,

then Landlord may treat the occurrence of any one (1) or more of the foregoing
events (each, an "EVENT OF DEFAULT") as a breach of this Lease and, in addition
to any or all other rights and remedies available to Landlord at law or in
equity, Landlord shall have the right, at Landlord's option, without further
notice or demand of any kind to Tenant or any other person, but subject to
complying with all Applicable Laws (i) to declare the Term ended and to re-enter
and take possession of the Premises and remove all persons therefrom, or (ii)
without declaring this Lease terminated and without terminating Tenant's right
to possession, to re-enter the Premises and occupy the whole or any part for and
on account of Tenant and to collect any unpaid rentals and other charges which
have become payable or which may thereafter become payable, or (iii) even though
it may have re-entered the Premises as provided in clause (ii) of this Section
13.1, to thereafter elect to terminate this Lease and all of the rights of
Tenant in or to the Premises. In

<PAGE>

any case in which Landlord shall re-enter and occupy the whole or any part of
the Premises, by unlawful detainer proceedings or otherwise, Landlord, at its
option, may repair, alter, subdivide or change the character of the Premises
from time to time in such manner as Landlord deems best, or may relet the
Premises or any part thereof and receive the rents therefor, and none of such
actions shall constitute a termination of this Lease or a release of Tenant from
any liability hereunder. Landlord shall not be deemed to have terminated this
Lease, or the liability of Tenant to pay any Monthly Rental, Additional Rental
or other charges later accruing, by any re-entry of the Premises pursuant to
clause (ii) of this Section 13.1, or by any action in unlawful detainer or
otherwise to obtain possession of the Premises, unless Landlord shall have
notified Tenant in writing that it has so elected to terminate this Lease.

      13.2 TERMINATION OF LEASE. Should Landlord elect to terminate this Lease
pursuant to the provisions of clauses (i) or (iii) of Section 13.1, Landlord may
recover from Tenant, as damages, the following: (a) the worth at the time of
award of any unpaid rental which had been earned at the time of the termination,
plus (b) the worth at the time of award of the amount by which the unpaid rental
which would have been earned after termination until the time of award exceeds
the amount of rental loss Tenant proves could have been reasonably avoided, plus
(c) the worth at the time of award of the amount by which the unpaid rental for
the balance of the Term after the time of award exceeds the amount of rental
loss that Tenant proves could be reasonably avoided, plus (d) any other amounts
necessary to compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its obligations under this Lease or which, in the
ordinary course of things, would be likely to result therefrom including, but
not limited to, any costs or expenses incurred by Landlord in (i) retaking
possession of the Premises, including, but not limited to, reasonable attorneys'
fees and court costs therefor, (ii) maintaining or preserving the Premises after
any default, (iii) preparing the Premises for reletting to a new tenant,
including, but not limited to, repairs or alterations to the Premises, (iv)
leasing commissions, or (v) any other costs necessary or appropriate to relet
the Premises, plus (e) at Landlord's election, any other amounts in addition to
or in lieu of the foregoing as may be permitted from time to time by applicable
laws.

      As used in subsections (a) and (b) of this Section 13.2, the "worth at the
time of award" is computed by allowing interest at the maximum lawful rate. As
used in subsection (c) of this Section 13.2, the "worth at the time of award" is
computed by discounting such amount at the discount rate of the Federal Reserve
Bank situated nearest to the location of the Premises at the time of award plus
one percent (1%).

      13.3 DEFINITION OF RENTAL. For purposes of this Lease, the term "rental"
shall be deemed to be Monthly Rental, Additional Rental and all other sums
required to be paid by Tenant pursuant to the terms of this Lease. All sums,
other than Monthly Rental, shall, for the purpose of calculating any amount due
under the provisions of subsection (c) of Section 13.2, be computed on the basis
of the average monthly amount accruing during the immediately preceding sixty
(60) month period, except that if it becomes necessary to compute these sums
before the sixty (60) month period has occurred, then these sums shall be
computed on the basis of the average monthly amount accruing during the shorter
period.

      13.4 NONMONETARY DEFAULTS. Notwithstanding any other provision of this
Article 13, if the default complained of, other than a default for the payment
of monies, cannot be rectified

<PAGE>

or cured within the period requiring rectification or curing, as specified in
the written notice relating to the default, then, as to a default susceptible to
being cured, the default shall be deemed to be rectified or cured if Tenant,
within the notice period, shall have commenced to rectify or cure the default
and shall thereafter diligently and continuously prosecute same to completion.

                                   ARTICLE 14
                              DEFAULTS BY LANDLORD

      14.1 LANDLORD'S LIABILITY. If Landlord fails to perform any of its
obligations contained in this Lease within thirty (30) days after written notice
from Tenant (or if more than thirty (30) days shall be required because of the
nature of the default, if Landlord shall fail to commence to cure the default
within said thirty (30) days or thereafter fail to diligently prosecute such
cure to completion), then (i) Landlord shall be liable to Tenant for all damages
sustained by Tenant as a result of Landlord's breach, (ii) Tenant shall have the
right to cure such default on Landlord's behalf and deduct all of Tenant's costs
and expenses incurred in connection with such cure from any amount of rental due
thereafter, (iii) Tenant shall be entitled to terminate this Lease as a result
thereof, and (iv) Tenant may pursue all rights and remedies available to Tenant
at law or equity. All of Tenant's rights and remedies under this Section shall
be cumulative. Landlord and Tenant agree that the provisions of this Section are
intended to supersede and replace the provisions of California Civil Code
Sections 1932(1), 1941 and 1942, and accordingly, Tenant hereby waives the
provisions of California Civil Code Sections 1932(1), 1941 and 1942 and/or any
similar or successor law regarding Tenant's right to terminate this Lease or to
make repairs and deduct the expenses of such repairs from the rent due under
this Lease.

      14.2 CURE BY LENDER. If any part of the Premises is at any time subject to
a first mortgage or a first deed of trust, and this Lease or the rentals due
from Tenant hereunder are assigned by Landlord to a mortgagee, trustee or
beneficiary (a "LENDER"), and if Tenant is given written notice of the
assignment including the mailing address of Lender, then Tenant shall also give
written notice of any default by Landlord to Lender, specifying the default in
reasonable detail and affording Lender the same cure period afforded Landlord to
make performance for and on behalf of Landlord. If, and when, Lender has made
performance on behalf of Landlord, the default shall be deemed cured.

      14.3 LIMITATION OF LIABILITY. Tenant agrees that, in the event Tenant
shall have any claim against Landlord under this Lease arising out of the
subject matter of this Lease, Tenant's sole recourse shall be against the
Landlord's interest in the Project, for the satisfaction of any claim, judgment
or decree requiring the payment of money by Landlord as a result of a breach
hereof or otherwise in connection with this Lease, and no other property or
assets of Landlord, its successors or assigns, shall be subject to the levy,
execution or other enforcement procedure for the satisfaction of any such claim,
judgment, injunction or decree. Tenant further hereby waives any and all right
to assert any claim against or obtain any damages from, for any reason
whatsoever, the constituent members, partners, directors, officers and trustees
of Landlord, including all injuries, damages or losses to Tenant's property,
real and personal, whether known, unknown, foreseen, unforeseen, patent or
latent, which Tenant may have against Landlord or its directors, officers or
trustees; provided, however, if Landlord is a partnership, the foregoing shall
not limit or impair Tenant's ability to name (but not pursue) the general
partner(s) in Landlord in

<PAGE>

any action brought against Landlord to the extent naming them is necessary to
bring such action against Landlord.

                                   ARTICLE 15
               SUBORDINATION, ATTORNMENT AND ESTOPPEL CERTIFICATE

      15.1 SUBORDINATION. If Tenant receives a non-disturbance agreement in a
form reasonably acceptable to Tenant allowing Tenant to remain in possession of
the Premises on the terms of this Lease after a foreclosure sale or deed in
lieu, then within ten (10) business days after receipt of written request of
Landlord, Tenant will subordinate its rights pursuant to this Lease in writing
to the lien of any mortgage or deed of trust (or, at Landlord's option, cause
the lien of said mortgage or deed of trust to be subordinated to this Lease),
and to all advances made or hereafter to be made upon the security thereof.

      15.2 ATTORNMENT. In the event any proceedings are brought for foreclosure,
or in the event of the exercise of the power of sale under any mortgage or deed
of trust made by Landlord encumbering the Premises, or should a lease in which
Landlord is the lessee be terminated, Tenant shall attorn to the purchaser or
lessor under such lease upon any foreclosure, sale or lease termination, and
shall recognize the purchaser or lessor as Landlord under this Lease, provided
that the purchaser or lessor shall acquire and accept the Premises subject to
this Lease.

      15.3 ESTOPPEL CERTIFICATE. Each party agrees, upon not less than ten (10)
business days prior written notice by the other, to execute, acknowledge and
deliver to the other, a statement in writing in such form as may be reasonably
required by either party's mortgagee or beneficiary or that is otherwise in a
form reasonably requested by the requesting party ("CERTIFICATE"). It is
intended that any Certificate delivered pursuant hereto may be relied upon by
the requesting party, any prospective tenant, subtenant or assignee of the
Premises, any current or prospective mortgagee or beneficiary, or by any other
party who may reasonably rely on such statement. At the requesting party's
option, the failure to deliver such Certificate within such time shall be
conclusively presumed, and shall constitute a representation and warranty by the
non-requesting party, that (a) this Lease is in full force and effect without
modification, and (b) the requesting party is not in breach of any of its
obligations under the Lease.

      15.4 NON-DISTURBANCE AGREEMENT. Upon execution of this Lease, Landlord
shall deliver to Tenant a non-disturbance agreement, executed by Landlord's
existing lender(s), in a form reasonably acceptable to Tenant that will allow
Tenant to remain in possession of the Premises on the terms of this Lease after
a foreclosure sale or deed in lieu, provided Tenant is not then in default under
this Lease beyond all applicable cure periods.

                            LANDLORD'S RIGHT OF ENTRY

      Provided Landlord shall strictly comply with Tenant's reasonable and
non-discriminatory corporate policies and rules and regulations, Landlord, its
agents, contractors, servants and employees may only enter the Premises with a

and after Landlord's good faith efforts to coordinate such entry with Tenant's
on-site management so as to minimize interference with Tenant's business

operations (except in a case of emergency in which event Landlord may enter at
any time without notice to Tenant) for the following purposes only: (a) to
examine the Premises to confirm Tenant's compliance with the terms of this
Lease; (b) to perform any obligation or exercise any right or remedy of Landlord
under this Lease (including, without limitation, Landlord's obligations under
Article 7 and Article 8 of this Lease); (c) to perform work necessary to comply
with laws, statutes, ordinances, rules or regulations of any governmental
authority that Landlord is required or permitted to perform hereunder; (d) to

detainer action and/or during the last one hundred twenty (120) days of the
Term, to show the Premises to prospective tenants and to post appropriate for
lease signs. In no event shall Landlord be permitted to enter Tenant's
restricted and/or confidential areas.

                                 QUIET ENJOYMENT

      Upon Tenant's payment of Monthly Rental and Additional Rental, and its
observation and performance of all of the terms, covenants and conditions of
this Lease to be observed and performed by Tenant, Tenant shall peaceably and
quietly hold and enjoy the Premises from and after delivery thereof to Tenant
without any hindrance or molestation from Landlord, Lender or any third party
throughout the Term.

                                   ARTICLE 18
                                     NOTICES

      All notices, demands, requests or other communications required or
permitted hereunder (collectively, "NOTICES") shall be in writing, shall be
addressed to the receiving party, with a copy to such party's counsel, if any,
as provided below in this Section, and shall be personally delivered, sent by
overnight mail (FedEx or another carrier that provides receipts for all
deliveries), sent by certified mail, postage prepaid, return receipt requested,
or sent by telecopy (except that any statutory notices delivered as a condition
to termination of this Lease or of Tenant's right to possession of the Premises
shall not be delivered by telecopy). All Notices shall be effective upon actual
receipt at the appropriate address. Notice of change of address shall be given
by written notice in the manner detailed in this Section. Rejection or other
refusal to accept or the inability to deliver due to changed address of which no
Notice in accordance with this Section was given shall be deemed to constitute
actual receipt of such Notice. The providing of copies of Notices to the
parties' respective counsels is for information only, is not required for valid
Notice and does not alone constitute Notice hereunder.

                                  MISCELLANEOUS

      19.1 WAIVER. Any waiver by either party of a breach by the other party of
a term, covenant or condition of this Lease shall not be construed as a waiver
of a subsequent breach of the same term, covenant or condition. The consent or
approval by either party to anything requiring such party's consent or approval
shall not be deemed a waiver of such party's right to withhold consent or
approval of any subsequent similar act. No breach of a term, covenant or
condition of this Lease shall be deemed to have been waived by the other party
unless the waiver is in writing and is signed by such party.

      19.2 RIGHTS CUMULATIVE. Except as expressly provided herein to the
contrary, the respective rights and remedies of the parties specified in this
Lease shall be cumulative and in addition to any rights and remedies not
specified in this Lease.

      19.3 ENTIRE AGREEMENT. Except as set forth in this Lease, there are no
oral or written agreements or representations between the parties hereto
relating to this Lease or the Premises, and this Lease supersedes and cancels
any and all previous negotiations, arrangements, representations, brochures,
agreements and understandings, if any, between Landlord and Tenant relating to
the leasing of the Premises from Landlord to Tenant.

      19.4 AMENDMENTS IN WRITING. No provision of this Lease may be amended
except by an agreement in writing signed by Landlord and Tenant.

      19.5 NO PRINCIPAL/AGENT RELATIONSHIP. Nothing contained in this Lease
shall be construed as creating the relationship of principal and agent or of
partnership or joint venture between Landlord and Tenant.

      19.6 LAWS OF CALIFORNIA TO GOVERN. This Lease is entered into and to be
performed entirely within the State of California and shall be governed by and
construed in accordance with

<PAGE>

the laws, statutes, rules and regulations of the State of California without
giving effect to the choice of law provisions thereof.

      19.7 SEVERABILITY. If any provision of this Lease or the application of
such provision to any person, entity or circumstance is found invalid or
unenforceable by a court of competent jurisdiction, such provision shall be
enforced to the fullest extent permitted by law, such determination shall not
affect the other provisions of this Lease, and all other provisions of this
Lease shall be deemed valid and enforceable.

      19.8 SUCCESSORS. All rights and obligations of Landlord and Tenant under
this Lease shall extend to and bind the respective heirs, executors,
administrators and the permitted concessionaires, successors, subtenants and
assignees of the parties.

      19.9 TIME OF THE ESSENCE. Time is of the essence of all provisions of this
Lease of which time is an element.

      19.10 WARRANTY OF AUTHORITY. If either Tenant or Landlord is a
corporation, limited liability company or partnership, each individual executing
this Lease on behalf of the corporation, limited liability company or
partnership represents and warrants that he or she is duly authorized to execute
and deliver this Lease on behalf of the corporation, limited liability company
or partnership and that this Lease is binding upon the corporation, limited
liability company or partnership.

      19.11 NO BROKERAGE COMMISSIONS. Tenant and Landlord each represent and
warrant to the other party that, except for Grubb & Ellis, whose commission (if
any) shall be paid by Tenant pursuant to a separate agreement, no broker or
finder can properly claim a right to a commission or finder's fee based upon
contacts between the claimant and the warranting party with respect to the other
party or the Premises. Tenant and Landlord shall indemnify, defend and hold each
other harmless from and against any loss, cost or expense, including, but not
limited to, attorneys' fees and court costs, resulting from any claim for a fee
or commission by any other broker or finder in connection with the Premises and
this Lease resulting from the indemnifying party's actions.

      19.12 RECORDING. At the request of Tenant, Landlord shall execute a short
form memorandum of this Lease for recording in the Official Records of Orange
County, California.

      19.13 TRANSFER OF LANDLORD'S INTEREST. Should Landlord sell, exchange or
assign this Lease (other than a conditional assignment as security for a loan),
then Landlord, as transferor, shall be relieved of any and all obligations on
the part of Landlord accruing under this Lease from and after the date of such
transfer provided that Landlord's successor in interest shall assume in writing
such obligations from and after such date. Landlord shall not be relieved of
liability for any obligations accruing prior to the date of such transfer.

      19.14 PERSONAL PROPERTY. Upon the expiration or earlier termination of the
Term, Tenant shall, at its sole cost and expense, remove from the Premises all
of Tenant's trade fixtures, furniture, equipment, signs, and other personal
property, however installed, affixed or attached to the Premises, and repair any
damage occasioned to the Premises by reason of such removal. Tenant may encumber
or finance its trade fixtures, furniture, equipment and other

<PAGE>

personal property installed or placed in the Premises, and no such encumbrance
or financing shall be deemed an Assignment, provided such encumbrance or
financing creates a security interest in such personal property only, and
confers no interest in the Premises.

      19.15 FORCE MAJEURE. Any prevention, delay or stoppage due to strikes,
lockouts, labor disputes, acts of God, inability to obtain labor or materials or
reasonable substitutes therefor, governmental restrictions, governmental
regulations, governmental controls, judicial orders, enemy or hostile
governmental action, civil commotion, fire or other casualty, and other causes
(except financial) beyond the reasonable control of the party obligated to
perform, shall excuse the performance by that party for a period equal to the
prevention, delay or stoppage, except the obligations imposed with regard to
Monthly Rental and Additional Rental to be paid by Tenant pursuant to this
Lease.

      19.16 TERMINATION AND HOLDING OVER. This Lease shall terminate without
further notice upon the expiration of the Term. Upon the expiration or earlier
termination of the Term, Tenant shall peaceably and quietly surrender the
Premises in the same condition as the Premises were in on the Commencement Date,
reasonable wear and tear, any damage to the Premises which Tenant is not
required to repair pursuant to Article 12, condemnation and Alterations not
required to be removed pursuant to this Lease excepted. Tenant shall repair all
damage to the Premises caused by Tenant's removal of Tenant's personal property,
trade fixtures, equipment, Alterations and any Signage. Should Tenant hold over
in the Premises beyond the expiration or earlier termination of this Lease, the
holding over shall not constitute a renewal or extension of this Lease or give
Tenant any rights under this Lease. In the event that the "Fair Market Rental
Rate" (as defined in the Other Lease) is not determined under the Other Lease,
due to no fault of Tenant, at least eight (8) months prior to the end of the New
Lease Option Term and Tenant thereafter elects not to exercise the New Lease
Renewal Term, then Monthly Rental shall remain at the rate determined pursuant
to Section 4.2 of the Lease for the same number of days after the expiration of
the New Lease Option Term as elapsed from and after the date which is eight (8)
months prior to the last day of the New Lease Option Term until such Fair Market
Rental Rate was determined. In such event, Landlord may, in its sole discretion,
either (a) upon written notice to Tenant, treat Tenant as a month-to-month
tenant at will, subject to all of the terms, covenants and conditions in this
Lease, except that Monthly Rental shall be an amount equal to one hundred twenty
five percent (125%) of the Monthly Rental which was payable by Tenant for the
twelve (12) month period immediately preceding the expiration or earlier
termination of this Lease, or (b) proceed with an unlawful detainer action and
pursue all other rights and remedies available to Landlord. Acceptance by
Landlord of any Monthly Rental or Additional Rental after the expiration or
earlier termination of this Lease shall not constitute a consent to a holdover
hereunder, constitute acceptance of Tenant as a tenant at will, or result in a
renewal of this Lease. Tenant shall not be liable to Landlord or any third party
for consequential damages (such as lost profits) as a result of any holdover by
Tenant.

      19.17 ATTORNEY'S FEES AND PROCESSING CHARGES. In the event that, at any
time after the date of this Lease, either Landlord or Tenant shall institute any
action or proceeding against the other relating to the provisions of this Lease
or any default hereunder, the party not prevailing in such action or proceeding
shall reimburse the prevailing party for its actual attorneys' fees, and all
fees, costs and expenses incurred in connection with such action or proceeding,
including, but not limited to, any post-judgment fees, costs or expenses
incurred on any appeal or in collection

<PAGE>

of any judgment and any fees, costs or expenses incurred in appearing in any
bankruptcy proceeding.

                                      LEASE

                                    EXAMPLES

      Unless expressly defined herein, all capitalized terms used herein shall
have the meanings ascribed to them in the East Tower Lease to which this Exhibit
E is attached.

      The examples set forth below are intended to set forth the steps that need
to be taken in (a) calculating the dollar amount of Tenant's Share of any
Capital Expense item payable by Tenant when a Capital Expense item is completed
or put in service, and (b) in calculating the dollar amount of the Applicable
Adjusted Uncovered Capital Expense Balance payable for such Capital Expense item
at the beginning of each Renewal Term. The following examples are only examples
and are not intended to amend or modify any of the terms of the Lease.

      In connection with the review of the examples set forth below and
understanding the steps taken therein , the following concepts should be kept in
mind:

      1. Each "UNCOVERED CAPITAL EXPENSE BALANCE" relates to a specific Capital
Expense item and, once determined, never changes. It constitutes the portion of
the Capital Expense item paid by the Landlord under Section 8.1(c)(ii) of the
Lease.

      2. The "ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE" changes at the
beginning of the Renewal Term (the beginning of the New Lease Option Term, if
any, and the beginning of the New Lease Renewal Term, if any) since it equals
the Uncovered Capital Expense Balance, less all payments received by Landlord
towards the Uncovered Capital Expense Balance, less the Lost Uncovered Capital
Expense Balance (which only comes into play when there is a reduction in
Premises at the inception of the Renewal Term, the New Lease Option Term, if
any, and the New Lease Renewal Term, if any). The Adjusted Uncovered Capital
Expense Balance is a measurement of that portion of the Uncovered Capital
Expense Balance for which Landlord has not yet received reimbursement, but is
expected to receive reimbursement by the end of the Useful Life of the Capital
Expense item provided the Premises are not reduced in any future Lease Years.

      3. The "APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE" is intended
to constitute the portion of the Adjusted Uncovered Capital Expense Balance that
is to be paid by the Tenant for the specific Renewal Term (and New Lease Option
Term, if any, and New Lease Renewal Term, if any) for which it is being
calculated.

      4. "TENANT'S PORTION" is different then "TENANT'S SHARE" in that "Tenant's
Share" is the portion of a Capital Expense item to be paid by Tenant when the
Capital Expense item is completed or put in service and "Tenant's Portion"
measures the square footage of the Premises leased by Tenant at the commencement
of a Renewal Term (and New Lease Option Term, if any, and New Lease Renewal
Term, if any), as compared to the square footage of the Premises leased by
Tenant immediately prior to such Renewal Term (or New Lease Option Term, if any,
or New Lease Renewal Term, if any). If the Premises include the entire East
Tower, Tenant's Portion

                                       1

<PAGE>

will be 100%. Also, if during the Renewal Term the Premises are 50% of the East
Tower, the Tenant's Portion will be 50% for the Renewal Term. As the Premises
shrink, the Adjusted Uncovered Capital Expense Balance also shrinks.

      5. At the end of the Useful Life of any Capital Expense item, the
Applicable Adjusted Uncovered Capital Expense Balance will equal 0.

EXAMPLE 1

ASSUMED FACTS

1. A Capital Expense item is incurred by Tenant in the amount of $200,000 and
completed on June 26, 2006. For purposes of making the calculations set forth
below, it is assumed that the initial term of the Other Lease commenced on
February 26, 2005 and terminates on February 25, 2015. The Capital Expense has a
Useful Life of 10 years.

2. The Tenant exercises its Renewal Option for the entire East Tower.

3. The Tenant exercises the New Lease Option for the entire East Tower.

APPLICATION OF FACTS TO SECTIONS 2.2(e), 2.3, 4.8(d), AND 8.1(d)

The $200,000 Capital Expense would be treated under Section 2.2(e), Section 2.3,
Section 4.8(d) and Section 8.1(d) of the Lease as follows:

      A.    STEP 1---DETERMINE LUMP SUM PAYMENT UPON COMPLETION OF THE CAPITAL
            EXPENSE ITEM (OR PUTTING THE SAME IN SERVICE). Pursuant to the
            provisions of Section 8.1(c) of the Lease, upon Tenant's demand in
            accordance with the Lease, 8/10 (or $160,000) of the Capital Expense
            item would be paid by the Landlord; Tenant would pay its share of
            $40,000 (2/10). The $160,000 paid by the Landlord would constitute
            the Uncovered Capital Expense Balance for the particular Capital
            Expense item.

      B.    STEP 2---DETERMINE LUMP SUM PAYMENT IN CONNECTION WITH THE RENEWAL
            TERM (SECTION 2.2(e)). In connection with Tenant's exercise of the
            Renewal Option for the entire East Tower, the Tenant would be
            obligated to pay to Landlord the Applicable Adjusted Uncovered
            Capital Expense Balance, which would be determined as follows:

            (i) ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION 2.2(e)).
            Uncovered Capital Expense Balances ($160,000), minus all amounts
            that have been paid by Tenant to reimburse Landlord for the
            Uncovered Capital Expense Balance (0), minus the Lost Uncovered
            Capital Expense Balance (0) = $160,000.

            (ii) APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION
            2(e)). Adjusted Uncovered Capital Expense Balance ($160,000),
            multiplied by a fraction, where

                                       2
<PAGE>

            x is the numerator and is 2 (in accordance with Section 2.2, x is
            the lesser of (1) the ensuing Renewal Term (which is 2), or (2) the
            Remaining Useful Life of the Capital Expense item (which is 8)), and

            y is the denominator and is 8 (the Remaining Useful Life of the
            Capital Expense item)

            = $160,000 X 2/8 = $40,000

Based upon the foregoing, the Applicable Adjusted Uncovered Capital Expense
Balance equals $40,000 and Tenant is obligated to pay such amount to Landlord as
Additional Rental on or before the first day of the Renewal Term. At the end of
the Renewal Term, the Adjusted Uncovered Capital Expense Balance will be
$120,000; such number would be the Adjusted Uncovered Capital Expense Balance
immediately before the New Lease Option is exercised.

      C.    STEP 3---DETERMINE LUMP SUM PAYMENT IN CONNECTION WITH NEW LEASE
            OPTION (SECTION 2.3(a)(iii)) In connection with Tenant's exercise of
            the New Lease Option for the entire East Tower, the Tenant would be
            obligated to pay to Landlord the Applicable Adjusted Uncovered
            Capital Expense Balance, which would be determined as follows:

            (i) ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION 2.2(e)).
            Uncovered Capital Expense Balances ($160,000), minus all amounts
            that have been paid by Tenant to reimburse Landlord for the
            Uncovered Capital Expense Balance ($40,000), minus the Lost
            Uncovered Capital Expense Balance (0) = $120,000.

            (ii) APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION
            2(e)). Adjusted Uncovered Capital Expense Balance ($120,000),
            multiplied by a fraction, where

            x is the numerator and is 56 (in accordance with Section 2.2, x is
            the lesser of (1) the New Lease Option Term (which is 56 months), or
            (2) the Remaining Useful Life of the Capital Expense item (which is
            72 months)), and

            y is the denominator and is 72 months (the Remaining Useful Life of
            the Capital Expense item)

            = $120,000 X 56/72 = $93,333

Based upon the foregoing, the Applicable Adjusted Uncovered Capital Expense
Balance equals $93,333 and Tenant is obligated to pay such amount to Landlord in
connection with the execution and delivery of the New Lease.

EXAMPLE 2

ASSUMED FACTS

1. A Capital Expense item is incurred by Tenant in the amount of $1,000,000 and
completed on June 26, 2006. For purposes of making the calculations set forth
below, it is assumed that the initial term of the Other Lease commenced on
February 26, 2005, and terminates on February 25,

                                       3
<PAGE>

2015; which means that the New Lease Option Term will be for 56 months. The
Capital Expense has a Useful Life of 20 years.

2. The Tenant exercises the Renewal Option for the entire East Tower, its New
Lease Option for 50% of the rentable square footage of the East Tower, and its
New Lease Renewal Option for 50% of the rentable square footage of the East
Tower.

APPLICATION OF FACTS TO SECTIONS 2.2(e), 2.3, 4.8(d), AND 8.1(d)

The $1,000,000 Capital Expense item would be treated under Section 2.2(e),
Section 2.3, Section 4.8(d) and Section 8.1(d) of the Lease as follows:

      A.    STEP 1---DETERMINE LUMP SUM PAYMENT UPON COMPLETION OF THE CAPITAL
            EXPENSE ITEM (OR PUTTING THE SAME IN SERVICE). Pursuant to the
            provisions of Section 8.1(c) of the Lease, upon Tenant's demand in
            accordance with the Lease, 18/20 (or $900,000) of the Capital
            Expense item would be paid by the Landlord; Tenant would pay its
            share of $100,000 (2/20). The $900,000 paid by the Landlord would
            constitute the Uncovered Capital Expense Balance for the particular
            Capital Expense item.

      B.    STEP 2---DETERMINE LUMP SUM PAYMENT PAYABLE ON THE FIRST DAY OF THE
            RENEWAL TERM (SECTION 2.2(e)). In connection with Tenant's exercise
            of the Renewal Option for the entire East Tower, the Tenant would be
            obligated to pay to Landlord the Applicable Adjusted Uncovered
            Capital Expense Balance, which would be determined as follows:

            (i) ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION 2.2(e)).
            Uncovered Capital Expense Balance ($900,000), minus all amounts that
            have been paid by Tenant to reimburse Landlord for the Uncovered
            Capital Expense Balance (0), minus the Lost Uncovered Capital
            Expense Balance (0) = $900,000.

            (ii) APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE (SECTION
            2.2(e)). Adjusted Uncovered Capital Expense Balance ($900,000),
            multiplied by a fraction, where

            x is the numerator and is 2 (in accordance with Section 2.2, x is
            the lesser of (1) the Renewal Term (which is 2), or (2) the
            Remaining Useful Life of the Capital Expense item (which is 18), and

            y is the denominator and is 18 (the Remaining Useful Life of the
            Capital Expense item)

            = $900,000 X 2/18 = $100,000

Based upon the foregoing, the Applicable Adjusted Uncovered Capital Expense
Balance equals $100,000 and Tenant is obligated to pay such amount to Landlord
as Additional Rental on or before the first day of the Renewal Term.

      C.    STEP 3--- DETERMINE AMORTIZED PAYMENTS DURING NEW LEASE OPTION TERM.
            In connection with Tenant's exercise of the New Lease Option for 50%
            of the East Tower, Tenant would be obligated to pay to Landlord the
            Applicable Adjusted Uncovered

                                       4
<PAGE>

            Capital Expense Balance on a monthly basis during the New Lease
            Option Term, as Building Operating Costs, which would be determined
            as follows:

            (i) LOST UNCOVERED CAPITAL EXPENSE BALANCES = the product of (a) 1,
            minus Tenant's Portion (1-.50=.50), multiplied by (b) the Adjusted
            Uncovered Capital Expense Balance existing immediately prior to
            making this calculation ($800,000) = $400,000 = LOST UNCOVERED
            EXPENSE BALANCE (since this is the only time Lost Uncovered Expense
            Balance has been calculated with a number greater than 0).

            (ii) ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE = Uncovered Capital
            Expense Balance ($900,000), minus all amounts that have been paid by
            Tenant to reimburse Landlord for the Uncovered Capital Expense
            Balance ($100,000), minus the Lost Uncovered Capital Expense Balance
            ($400,000) = $400,000.

            (iii) APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE =
            Adjusted Uncovered Capital Expense Balance ($400,000), multiplied by
            a fraction, where

            x is the numerator and is 56 (in accordance with Section 2.2, x is
            the lesser of (1) the New Lease Option Term (which is 56 months) or
            (2) the Remaining Useful Life of the Capital Expense item (which is
            192 months or 16 years), and

            y is the denominator and is 192 months (the Remaining Useful Life of
            the Capital Expense item)

            = $400,000 X 56/192 = $116,666 = APPLICABLE ADJUSTED UNCOVERED
            CAPITAL EXPENSE BALANCE

            (iv) PAYMENT OF APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE
            BALANCE THROUGH THE MONTHLY PAYMENT OF BUILDING OPERATING COSTS
            (SECTION 2.3(a)(iii))) = $116,666 (Applicable Adjusted Uncovered
            Capital Expense Balance), multiplied by 1/56 = $2083.32

Based upon the foregoing, the Applicable Adjusted Uncovered Capital Expense
Balance equals $116,666 as of the beginning of the New Lease Option Term and
Tenant is obligated to pay such amount as part of Building Operating Costs at
the rate of $2,083.32 per month during the New Lease Option Term.

      D.    STEP 4--- DETERMINE AMORTIZED PAYMENTS DURING NEW LEASE RENEWAL
            TERM. In connection with Tenant's exercise of the New Lease Renewal
            Option for 50% of the East Tower, Tenant would be obligated to pay
            to Landlord the Applicable Adjusted Uncovered Capital Expense
            Balance on a monthly basis during the New Lease Renewal Term as
            Building Operating Costs, which amount would be determined as
            follows:

            (i) LOST UNCOVERED CAPITAL EXPENSE BALANCES = $400,000 (which was
            determined as a result of the calculation in C(i) above and which
            has not changed).

            (ii) ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCES = Uncovered Capital
            Expense Balance ($900,000), minus all amounts that have been paid by
            Tenant to reimburse

                                       5
<PAGE>

            Landlord for the Uncovered Capital Expense Balance ($100,000, plus
            $116,666 = $216,666), minus the Lost Uncovered Expense Balance
            ($400,000, which was determined as a result of the calculation in
            C(i) above) = $283,334.

            (iii) APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE BALANCE =
            Adjusted Uncovered Capital Expense Balance ($283,334), multiplied by
            a fraction, where

            x is the numerator and is 60 (in accordance with Section 2.2, x is
            the lesser of (1) the New Lease Renewal Term (which is 60 months) or
            (2) the Remaining Useful Life of the Capital Expense item (which is
            136 months), and

            y is the denominator and is 136 months (the Remaining Useful Life of
            the Capital Expense item)

            = $283,334 X 60/136 = $125,000 = APPLICABLE ADJUSTED UNCOVERED
            CAPITAL EXPENSE BALANCE

            (iv) PAYMENT OF APPLICABLE ADJUSTED UNCOVERED CAPITAL EXPENSE
            BALANCE THROUGH MONTHLY PAYMENT OF BUILDING OPERATING COSTS (SECTION
            2.3(b))) = $125,000 (Applicable Adjusted Uncovered Capital Expense
            Balances), multiplied by 1/60 = $2,083.33

Based upon the foregoing, the Applicable Adjusted Uncovered Capital Expense
Balance equals $125,000 as of the beginning of the New Lease Renewal Term and
Tenant is obligated to pay such amount as part of Building Operating Costs at
the rate of $2,083.33 per month during the New Lease Renewal Term.

                            INDEMNIFICATION AGREEMENT

           INDEMNIFICATION AGREEMENT, dated as of June 27, 2003 by and between
MINDSPEED TECHNOLOGIES, INC., a Delaware corporation (the "Corporation"), and
_______________, a director and/or officer of the Corporation ("Indemnitee").

                                    RECITALS

           WHEREAS, the Corporation desires to attract and retain the services
of highly qualified individuals to serve the Corporation and its related
entities;

           WHEREAS, the Corporation and Indemnitee recognize that highly
competent persons are becoming more reluctant to serve as directors or officers
or in other capacities with corporations unless they are provided with
reasonable protection through liability insurance or indemnification against
risks of claims and actions against them arising out of their service to and
activities on behalf of the corporations they serve;

           WHEREAS, the Corporation and Indemnitee further recognize the
substantial increase in corporate litigation in general, subjecting directors,
officers, employees and agents of corporations to expensive litigation risks at
the same time as the availability and coverage of liability insurance has been
severely limited and the cost of such insurance has increased significantly;

           WHEREAS, Article III, Section 14 of the Corporation's bylaws as in
effect on the date hereof (including the procedures attached as an Appendix
thereto) provides for indemnification and advancement of expenses of directors,
officers, employees and agents to the maximum extent permitted by Delaware law
as in effect on the date hereof;

           WHEREAS, the Board of Directors of the Corporation (the "Board of
Directors") has determined that the Corporation should act to assure its
directors and officers of such protection in order to enhance their continued
and effective service to the Corporation; and

           WHEREAS, in order to induce Indemnitee to provide such services to
the Corporation as a director and/or officer, the Corporation desires to enter
into this Agreement with Indemnitee providing for indemnification and
advancement of expenses as set forth herein;

<PAGE>

           NOW, THEREFORE, the Corporation and Indemnitee hereby agree as set
forth below.

                                    AGREEMENT

for, and save, defend and hold Indemnitee harmless from and against, any
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by Indemnitee as provided in Article
III, Section 14 and the Procedures and, to the extent the laws of the State of
Delaware may from time to time hereafter be amended to increase the scope of
such permitted indemnification, to the fullest extent of such laws.

           4. Non-Exclusivity. The rights of indemnification and to receive
advances as provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under or by reason
of applicable law, any certificate of incorporation or bylaws, any agreement,
any vote of stockholders or any

resolution of directors or otherwise. To the extent Indemnitee would be
prejudiced thereby, no amendment, alteration, rescission or replacement of this
Agreement or any provision hereof shall be effective as to Indemnitee with
respect to any action taken or omitted by such Indemnitee in Indemnitee's
position with the Corporation or any other entity which Indemnitee is or was
serving at the request of the Corporation prior to such amendment, alteration,
rescission or replacement.

Corporation and its successors and assigns and shall inure to the benefit of
Indemnitee and Indemnitee's spouse, assigns, heirs, devisee, executors,

           6. Severability. Should any part, term or condition hereof be
declared illegal or unenforceable or in conflict with any law, the validity of
the remaining portions or provisions of this Agreement shall not be affected
thereby, and the illegal or unenforceable portions of the Agreement shall be and
hereby are redrafted to conform with applicable law, while leaving the remaining
portions of this Agreement intact.

           7. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same document.

this Agreement.

of this Agreement shall be binding unless executed in writing by each of the
parties hereto. A waiver by any party of any breach or violation of this
Agreement shall not be deemed or construed as a waiver of any other or
subsequent breach or violation thereof.

           10. No Duplicative Payment. The Corporation shall not be liable under
this Agreement to make any payment of amounts otherwise indemnifiable hereunder
if and to the extent that Indemnitee has otherwise actually received such

                                   ARTICLE III

                                     OF THE

                     BYLAWS OF MINDSPEED TECHNOLOGIES, INC.

                                    * * * * *

           SECTION 14. INDEMNIFICATION. (A) The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation), by reason of the fact that such person is or was a
director, officer, employee or agent of the Corporation or any of its
majority-owned subsidiaries or is or was serving at the request of the
Corporation as a director, officer, employee or agent (except in each of the
foregoing situations to the extent any agreement, arrangement or understanding
of agency contains provisions that supersede or abrogate indemnification under
this section) of another corporation or of any partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his or her conduct was unlawful.

           (B) The Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the Corporation to procure a judgment in
its favor by reason of the fact that such person is or was a director, officer,
employee or agent of the Corporation or any of its majority-owned subsidiaries,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent (except in each of the foregoing situations to the extent any
agreement, arrangement or understanding of agency contains provisions that
supersede or abrogate indemnification under this section) of another corporation
or of any partnership, joint venture, trust, employee benefit plan or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the

                                      A-1
<PAGE>

best interests of the Corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery of Delaware or such other court shall deem proper.

           (C) To the extent that a director, officer, employee or agent of the
Corporation or any of its majority-owned subsidiaries has been successful on the
merits or otherwise in defense of any action, suit or proceeding referred to in
subsections (A) and (B), or in defense of any claim, issue or matter therein,
such person shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by or on behalf of such person in connection
therewith. If any such person is not wholly successful in any such action, suit
or proceeding but is successful, on the merits or otherwise, as to one or more
but less than all claims, issues or matters therein, the Corporation shall
indemnify such person against all expenses (including attorneys' fees) actually
and reasonably incurred by or on behalf of such person in connection with each
claim, issue or matter that is successfully resolved. For purposes of this
subsection and without limitation, the termination of any claim, issue or matter
by dismissal, with or without prejudice, shall be deemed to be a successful
result as to such claim, issue or matter.

           (D) Notwithstanding any other provision of this section, to the
extent any person is a witness in, but not a party to, any action, suit or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that such person is or was a director, officer, employee or agent of
the Corporation or any of its majority-owned subsidiaries, or is or was serving
at the request of the Corporation as a director, officer, employee or agent
(except in each of the foregoing situations to the extent any agreement,
arrangement or understanding of agency contains provisions that supersede or
abrogate indemnification under this section) of another corporation or of any
partnership, joint venture, trust, employee benefit plan or other enterprise,
such person shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by or on behalf of such person in
connection therewith.

           (E) Indemnification under subsections (A) and (B) shall be made only
as authorized in the specific case upon a determination that indemnification of
the director, officer, employee or agent is proper in the circumstances because
such person has met the applicable standard of conduct set forth in subsections
(A) and (B). Such determination shall be made (1) if a Change of Control (as
hereinafter defined) shall not have occurred, (a) with respect to a person who
is a present or former director or officer of the Corporation, (i) by the Board
of Directors by a majority vote of the Disinterested

                                      A-2
<PAGE>

Directors (as hereinafter defined), even though less than a quorum, or (ii) if
there are no Disinterested Directors or, even if there are Disinterested
Directors, a majority of such Disinterested Directors so directs, by (x)
Independent Counsel (as hereinafter defined) in a written opinion to the Board
of Directors, a copy of which shall be delivered to the claimant, or (y) the
shareholders of the Corporation; or (b) with respect to a person who is not a
present or former director or officer of the Corporation, by the chief executive
officer of the Corporation or by such other officer of the Corporation as shall
be designated from time to time by the Board of Directors; or (2) if a Change of
Control shall have occurred, by Independent Counsel selected by the claimant in
a written opinion to the Board of Directors, a copy of which shall be delivered
to the claimant, unless the claimant shall request that such determination be
made by or at the direction of the Board of Directors (in the case of a claimant
who is a present or former director or officer of the Corporation) or by an
officer of the Corporation authorized to make such determination (in the case of
a claimant who is not a present or former director or officer of the
Corporation), in which case it shall be made in accordance with clause (1) of
this sentence. Any claimant shall be entitled to be indemnified against the
expenses (including attorneys' fees) actually and reasonably incurred by such
claimant in cooperating with the person or entity making the determination of
entitlement to indemnification (irrespective of the determination as to the
claimant's entitlement to indemnification) and, to the extent successful, in
connection with any litigation or arbitration with respect to such claim or the
enforcement thereof.

           (F) If a Change of Control shall not have occurred, or if a Change of
Control shall have occurred and a director, officer, employee or agent requests
pursuant to clause (2) of the second sentence in subsection (E) that the
determination as to whether the claimant is entitled to indemnification be made
by or at the direction of the Board of Directors (in the case of a claimant who
is a present or former director or officer of the Corporation) or by an officer
of the Corporation authorized to make such determination (in the case of a
claimant who is not a present or former director or officer of the Corporation),
the claimant shall be conclusively presumed to have been determined pursuant to
subsection (E) to be entitled to indemnification if (1) in the case of a
claimant who is a present or former director or officer of the Corporation,
(a)(i) within fifteen days after the next regularly scheduled meeting of the
Board of Directors following receipt by the Corporation of the request therefor,
the Board of Directors shall not have resolved by majority vote of the
Disinterested Directors to submit such determination to (x) Independent Counsel
for its determination or (y) the shareholders for their determination at the
next annual meeting, or any special meeting that may be held earlier, after such
receipt, and (ii) within sixty days after receipt by the Corporation of the
request therefor (or within ninety days after such receipt if the Board of
Directors in good faith determines that additional time is required by it for
the determination and, prior to expiration of such sixty-day period, notifies
the claimant thereof), the Board of Directors

                                      A-3
<PAGE>

shall not have made the determination by a majority vote of the Disinterested
Directors, or (b) after a resolution of the Board of Directors, timely made
pursuant to clause (a)(i)(y) above, to submit the determination to the
shareholders, the shareholders meeting at which the determination is to be made
shall not have been held on or before the date prescribed (or on or before a
later date, not to exceed sixty days beyond the original date, to which such
meeting may have been postponed or adjourned on good cause by the Board of
Directors acting in good faith), or (2) in the case of a claimant who is not a
present or former director or officer of the Corporation, within sixty days
after receipt by the Corporation of the request therefor (or within ninety days
after such receipt if an officer of the Corporation authorized to make such
determination in good faith determines that additional time is required for the
determination and, prior to expiration of such sixty-day period, notifies the
claimant thereof), an officer of the Corporation authorized to make such
determination shall not have made the determination; provided, however, that
this sentence shall not apply if the claimant has misstated or failed to state a
material fact in connection with his or her request for indemnification. Such
presumed determination that a claimant is entitled to indemnification shall be
deemed to have been made (I) at the end of the sixty-day or ninety-day period
(as the case may be) referred to in clause (1)(a)(ii) or (2) of the immediately
preceding sentence or (II) if the Board of Directors has resolved on a timely
basis to submit the determination to the shareholders, on the last date within
the period prescribed by law for holding such shareholders meeting (or a
postponement or adjournment thereof as permitted above).

           (G) Expenses (including attorneys' fees) incurred in defending a
civil, criminal, administrative or investigative action, suit or proceeding
shall be paid by the Corporation in advance of the final disposition of such
action, suit or proceeding to a present or former director or officer of the
Corporation, promptly after receipt of a request therefor stating in reasonable
detail the expenses incurred, and to a person who is not a present or former
director or officer of the Corporation as authorized by the chief executive
officer of the Corporation or such other officer of the Corporation as shall be
designated from time to time by the Board of Directors; provided that in each
case the Corporation shall have received an undertaking by or on behalf of the
present or former director, officer, employee or agent to repay such amount if
it shall ultimately be determined that such person is not entitled to be
indemnified by the Corporation as authorized in this section.

           (H) The Board of Directors shall establish reasonable procedures for
the submission of claims for indemnification pursuant to this section,
determination of the entitlement of any person thereto and review of any such
determination. Such procedures shall be set forth in an appendix to these bylaws
and shall be deemed for all purposes to be a part hereof.

that any individual becoming a director subsequent to that date whose election,

vote of at least a majority of the directors then comprising the Incumbent Board
shall be considered as though such individual were a member of the Incumbent
Board, but excluding, for this purpose, any such individual whose initial
assumption of office occurs as a result of an actual or threatened election
contest with respect to the election or removal of directors or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person other
than the Board of Directors; or

                      (c) Consummation of a reorganization, merger or

"Corporate Transaction"), in each case, unless, following such Corporate
Transaction, (i) all or substantially all of the individuals and entities who

Corporate Transaction beneficially own, directly or indirectly, more than 60%
of, respectively, the then outstanding shares of common stock and the combined

generally in the election of directors, as the case may be, of the corporation
resulting from such Corporate Transaction (including, without limitation, a
corporation which as a result of such

                                      A-5
<PAGE>

transaction owns the Corporation or all or substantially all of the
Corporation's assets either directly or through one or more subsidiaries) in

(excluding Conexant Systems, Inc., any employee benefit plan (or related trust)
of the Corporation, of Conexant Systems, Inc. or of such corporation resulting
from such Corporate Transaction) beneficially owns, directly or indirectly, 20%
or more of, respectively, the then outstanding shares of common stock of the
corporation resulting from such Corporate Transaction or the combined voting
power of the then outstanding voting securities of such corporation except to
the extent that such ownership existed prior to the Corporate Transaction and
(iii) at least a majority of the members of the board of directors of the
corporation resulting from such Corporate Transaction were members of the
Incumbent Board at the time of the execution of the initial agreement, or of the
action of the Board of Directors, providing for such Corporate Transaction; or

complete liquidation or dissolution of the Corporation.

                      (2) "Disinterested Director" means a director of the
Corporation who is not and was not a party to an action, suit or proceeding in

                      (3) "Independent Counsel" means a law firm, or a member of

Corporation, the director, officer, employee or agent claiming indemnification
or any other party to the action, suit or proceeding giving rise to a claim for
indemnification under this section, in any matter material to the Corporation,
the claimant or any such other party; and (iii) would not, under applicable
standards of professional conduct then prevailing, have a conflict of interest
in representing either the Corporation or such director, officer, employee or
agent in an action to determine the Corporation's or such person's rights under
this section.

           (J) The indemnification and advancement of expenses herein provided,
or granted pursuant hereto, shall not be deemed exclusive of any other rights to
which any of those indemnified or eligible for advancement of expenses may be
entitled under any agreement, vote of shareholders or Disinterested Directors or
otherwise, both as to action in such person's official capacity and as to action
in another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such person.
Notwithstanding any amendment, alteration or repeal of this section or any of
its provisions, or of any of the procedures established by the Board of

indemnification of expenses relating to the enforcement of rights under this
section and such procedures.

                          PROCEDURES FOR SUBMISSION AND
                   DETERMINATION OF CLAIMS FOR INDEMNIFICATION
               PURSUANT TO ARTICLE III, SECTION 14 OF THE BYLAWS.

           SECTION 1. PURPOSE. The Procedures for Submission and Determination
of Claims for Indemnification Pursuant to Article III, Section 14 of the bylaws
(the "Procedures") are to implement the provisions of Article III, Section 14 of
the bylaws of the Corporation (the "bylaws") in compliance with the requirement
of subsection (H) thereof.

           SECTION 2. DEFINITIONS. For purposes of these Procedures:

           (A) All terms that are defined in Article III, Section 14 of the
bylaws shall have the meanings ascribed to them therein when used in these
Procedures unless otherwise defined herein.

           (B) "Expenses" include all reasonable attorneys' fees, court costs,
transcript costs, fees of experts, witness fees, travel expenses, duplicating
costs, printing and binding costs, telephone charges, postage, delivery service
fees, and all other disbursements or expenses of the types customarily incurred
in connection with prosecuting, defending, preparing to prosecute or defend,
investigating, or being or preparing to be a witness in, a Proceeding; and shall
also include such retainers as counsel may reasonably require in advance of
undertaking the representation of an Indemnitee in a Proceeding.

           (C) "Indemnitee" includes any person who was or is, or is threatened
to be made, a witness in or a party to any Proceeding by reason of the fact that
such person is or was a director, officer, employee or agent of the Corporation
or any of its majority-owned subsidiaries or is or was serving at the request of
the Corporation as a director, officer, employee or agent (except in each of the

                                      A-8
<PAGE>

           SECTION 3. SUBMISSION AND DETERMINATION OF CLAIMS.

           (A) To obtain indemnification or advancement of Expenses under
Article III, Section 14 of the bylaws, an Indemnitee shall submit to the
Secretary of the Corporation a written request therefor, including therein or
therewith such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to permit a determination as to whether
and what extent the Indemnitee is entitled to indemnification or advancement of
Expenses, as the case may be. The Secretary shall, promptly upon receipt of a
request for indemnification, advise the Board of Directors (if the Indemnitee is
a present or former director or officer of the Corporation) or the officer of
the Corporation authorized to make the determination as to whether an Indemnitee
is entitled to indemnification (if the Indemnitee is not a present or former
director or officer of the Corporation) thereof in writing if a determination in
accordance with Article III, Section 14(E) of the bylaws is required.

           (B) Upon written request by an Indemnitee for indemnification
pursuant to Section 3(A) hereof, a determination with respect to the
Indemnitee's entitlement thereto in the specific case, if required by the
bylaws, shall be made in accordance with Article III, Section 14(E) of the
bylaws, and, if it is so determined that the Indemnitee is entitled to
indemnification, payment to the Indemnitee shall be made within ten days after
such determination. The Indemnitee shall cooperate with the person, persons or
entity making such determination, with respect to the Indemnitee's entitlement
to indemnification, including providing to such person, persons or entity upon
reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably
available to the Indemnitee and reasonably necessary to such determination.

           (C) If entitlement to indemnification is to be made by Independent
Counsel pursuant to Article III, Section 14(E) of the bylaws, the Independent
Counsel shall be selected as provided in this Section 3(C). If a Change of
Control shall not have occurred, the Independent Counsel shall be selected by
the Board of Directors, and the Corporation shall give written notice to the
Indemnitee advising the Indemnitee of the identity of the Independent Counsel so
selected. If a Change of Control shall have occurred, the Independent Counsel
shall be selected by the Indemnitee (unless the Indemnitee shall request that
such selection be made by the Board of Directors, in which event the immediately
preceding sentence shall apply), and the Indemnitee shall give written notice to
the Corporation advising it of the identity of the Independent Counsel so
selected. In either event, the Indemnitee or the Corporation, as the case may
be, may, within seven days after such written notice of selection shall have
been given, deliver to the Corporation or to the Indemnitee, as the case may be,
a written objection to such selection. Such objection may be asserted only on
the ground that the Independent Counsel so selected does not meet the
requirements of "Independent Counsel" as defined

                                      A-9
<PAGE>

in Article III, Section 14 of the bylaws, and the objection shall set forth with
particularity the factual basis of such assertion. If such written objection is
made, the Independent Counsel so selected may not serve as Independent Counsel
unless and until a court has determined that such objection is without merit.
If, within twenty days after the next regularly scheduled Board of Directors
meeting following submission by the Indemnitee of a written request for
indemnification pursuant to Section 3(A) hereof, no Independent Counsel shall
have been selected and not objected to, either the Corporation or the Indemnitee
may petition the Court of Chancery of the State of Delaware or other court of
competent jurisdiction for resolution of any objection which shall have been
made by the Corporation or the Indemnitee to the other's selection of
Independent Counsel and/or for the appointment as Independent Counsel of a
person selected by the Court or by such other person as the Court shall
designate, and the person with respect to whom an objection is favorably
resolved or the person so appointed shall act as Independent Counsel under
Article III, Section 14(E) of the bylaws. The Corporation shall pay any and all
reasonable fees and expenses (including without limitation any advance retainers
reasonably required by counsel) of Independent Counsel incurred by such
Independent Counsel in connection with acting pursuant to Article III, Section
14(E) of the bylaws, and the Corporation shall pay all reasonable fees and
expenses (including without limitation any advance retainers reasonably required
by counsel) incident to the procedures of Article III, Section 14(E) of the
bylaws and this Section 3(C), regardless of the manner in which Independent
Counsel was selected or appointed. Upon the delivery of its opinion pursuant to
Article III, Section 14 of the bylaws or, if earlier, the due commencement of
any judicial proceeding or arbitration pursuant to Section 4(A)(3) of these
Procedures, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of
professional conduct then prevailing).

           (D) If a Change of Control shall have occurred, in making a
determination with respect to entitlement to indemnification under the bylaws,
the person, persons or entity making such determination shall presume that an
Indemnitee is entitled to indemnification under the bylaws if the Indemnitee has
submitted a request for indemnification in accordance with Section 3(A) hereof,
and the Corporation shall have the burden of proof to overcome that presumption
in connection with the making by any person, persons or entity of any
determination contrary to that presumption.

           SECTION 4. REVIEW AND ENFORCEMENT OF DETERMINATION.

           (A) In the event that (1) advancement of Expenses is not timely made
pursuant to Article III, Section 14(G) of the bylaws, (2) payment of
indemnification is not made pursuant to Article III, Section 14(C) or (D) of the
bylaws within ten days after receipt by the Corporation of written request
therefor, (3) a determination is made pursuant to Article III, Section 14(E) of
the bylaws that an Indemnitee is not entitled to

                                      A-10
<PAGE>

indemnification under the bylaws, (4) the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Article III,
Section 14(E) of the bylaws and such determination shall not have been made and
delivered in a written opinion within ninety days after receipt by the
Corporation of the written request for indemnification, or (5) payment of
indemnification is not made within ten days after a determination has been made
pursuant to Article III, Section 14(E) of the bylaws that an Indemnitee is
entitled to indemnification or within ten days after such determination is
deemed to have been made pursuant to Article III, Section 14(F) of the bylaws,
the Indemnitee shall be entitled to an adjudication in an appropriate court of
the State of Delaware, or in any other court of competent jurisdiction, of the
Indemnitee's entitlement to such indemnification or advancement of Expenses.
Alternatively, the Indemnitee, at his or her option, may seek an award in
arbitration to be conducted by a single arbitrator pursuant to the rules of the
American Arbitration Association. The Indemnitee shall commence such proceeding
seeking an adjudication or an award in arbitration within one year following the
date on which the Indemnitee first has the right to commence such proceeding
pursuant to this Section 4(A). The Corporation shall not oppose the Indemnitee's
right to seek any such adjudication or award in arbitration.

           (B) In the event that a determination shall have been made pursuant
to Article III, Section 14(E) of the bylaws that an Indemnitee is not entitled
to indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 4 shall be conducted in all respects as a de novo trial, or
arbitration, on the merits and the Indemnitee shall not be prejudiced by reason
of that adverse determination. If a Change of Control shall have occurred, the
Corporation shall have the burden of proving in any judicial proceeding or
arbitration commenced pursuant to this Section 4 that the Indemnitee is not
entitled to indemnification or advancement of Expenses, as the case may be.

           (C) If a determination shall have been made or deemed to have been
made pursuant to Article III, Section 14(E) or (F) of the bylaws that an
Indemnitee is entitled to indemnification, the Corporation shall be bound by
such determination in any judicial proceeding or arbitration commenced pursuant
to this Section 4, absent (1) a misstatement or omission of a material fact in
connection with the Indemnitee's request for indemnification, or (2) a
prohibition of such indemnification under applicable law.

           (D) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 4 that the
procedures and presumptions of these Procedures are not valid, binding and
enforceable, and shall stipulate in any such judicial proceeding or arbitration
that the Corporation is bound by all the provisions of these Procedures.

           (E) In the event that an Indemnitee, pursuant to this Section 4,
seeks to enforce the Indemnitee's rights under, or to recover damages for breach
of, Article III, Section 14 of the bylaws or these Procedures in a judicial
proceeding or arbitration, the Indemnitee shall be entitled to recover from the
Corporation, and shall be indemnified by the Corporation against, any and all
expenses (of the types described in the definition of Expenses in Section 2 of
these Procedures) actually and reasonably incurred in such judicial proceeding
or arbitration, but only if the Indemnitee prevails therein. If it shall be
determined in such judicial proceeding or arbitration that the Indemnitee is
entitled to receive part but not all of the indemnification or advancement of
Expenses sought, the expenses incurred by the Indemnitee in connection with such
judicial proceeding or arbitration shall be appropriately prorated.

           SECTION 5. AMENDMENTS. These Procedures may be amended at any time
and from time to time in the same manner as any bylaw of the Corporation in
accordance with the Certificate of Incorporation; provided, however, that
notwithstanding any amendment, alteration or repeal of these Procedures or any
provision hereof, any Indemnitee shall be entitled to utilize these Procedures
with respect to any claim for indemnification arising out of any action taken or
omitted prior to such amendment, alteration or repeal except to the extent
otherwise required by law.
