Hundred Thousand Dollars ($100,000.00) and limitation for injury or death per
occurrence not less than One Million Dollars ($1,000,000.00), and in the event

be filed with Landlord within ten (10) days following the execution of this
Lease by Landlord or prior to Tenant's occupancy of the Leased Premises,
whichever occurs first, and said policy shall provide that such insurance
coverage shall not be canceled or subject to reduction of coverage without at
least ten (10) days prior written notice to Landlord. At least thirty (30) days
prior to the expiration of any policy, a policy showing that such coverage has
been renewed or extended shall be filed with Landlord.

obligations hereunder, subsequent to the date of such damage. In the event that

not pay any sum payable by Tenant to Landlord after such sum becomes due and
payable under this Lease, or if Tenant fails to perform any of Tenant's other
covenants or provisions or agreements under this Lease. If Tenant does not cure
such default within three (3) days after written notice from Landlord, Landlord
shall have, in addition to any other rights hereunder, the right, without
further notice, and in addition to and not in lieu of other remedies available,
to terminate all of Tenant's rights under this Lease, or such of those rights as
Landlord designates in such written notice. Such notice shall be in lieu of, and
not in addition to, any notice required by California CODE OF CIVIL PROCEDURE
1161 or any other successor statute.

         If Tenant's rights under this Lease are so terminated, Landlord may,
after complying with any applicable requirements of law, take possession of the
Premises. Upon any such action by Landlord, Tenant shall remain liable for all
obligations which have previously accrued, and, to the maximum extent permitted
by law, for all obligations which may subsequently accrue under this Lease.

<PAGE>

to perform obligations required of Landlord within a reasonable time, but in no
event later than thirty days (30) after written notice by Tenant to Landlord,
specifying the nature of said default; provided, however, that if Landlord's
obligation is such that more than thirty days (30) is required for said
performance, then Landlord shall not be in default if Landlord commences
performance within said thirty day (30) period and thereafter diligently
prosecutes the same to completion.

         189.     FORCE MAJEURE: If Landlord's performance of this Lease or of
any of its obligations hereunder is prevented or restricted by reason of any
cause beyond the reasonable control of Landlord, including, but not limited to,
mechanical or electrical breakdown, fire, explosion or other casualty, acts of
God, acts of public enemies, embargo, delays of supplies, acts of any
governmental agency, labor difficulties, strikes or inclement weather, Landlord,
upon giving timely notice to Tenant, shall be excused from such performance
hereunder to the extent of such breakdown, prevention or restriction, provided
that Landlord shall resume performance within a reasonable time after any such
cause has been removed or ceases.

         1920.    ASSIGNMENT AND SUBLETTING: Tenant shall not assign this Lease
or any interest herein or sublet the Premises or any portion thereof or permit
any other person to occupy the Premises or any portion thereof. No assignee for
the benefit of creditors, trustee in bankruptcy or purchaser at any execution
sale shall have any right to possess or occupy the Premises or any part thereof,
or claim of right hereunder.

         Notwithstanding the foregoing, in the event that Landlord should
hereafter grant to Tenant permission to seek to assign or sublet, Tenant agrees
to reimburse Landlord's reasonable attorneys' fees incurred in connection with
the processing and documentation of any requested transfer, assignment, or
subletting agreement. Said Landlord's permission to seek to assign or sublet
must be in writing. Further, Landlord reserves the right to approve any
sub-tenant or assignee, and may demand any documentation whatsoever to
Landlord's satisfaction in order to approve said sub-tenant or assignee.
Further, Landlord may deny said approval solely within Landlord's discretion and
applicable law.

         201      TERMINATION: TENANT SHALL GIVE LANDLORD NOT LESS THAN SIXTY
(60) DAYS WRITTEN NOTICE OF TENANT'S INTENTION TO DISCONTINUE ITS TENANCY
HEREUNDER PRIOR TO THE END OF ANY TERM. IF TENANT FAILS TO PROVIDE SUCH NOTICE,
TENANT'S TERM SHALL AUTOMATICALLY BE RENEWED FOR AN ADDITIONAL ONE YEAR TERM.
TENANT'S CONTINUED FAILURE TO PROVIDE LANDLORD SUCH NOTICE WILL RESULT IN
TENANT'S TERM BEING AUTOMATICALLY RENEWED FOR SUCCESSIVE ADDITIONAL ONE YEAR
TERMS. SAID NOTICE MAY NOT BE GIVEN MORE THAN NINETY (90) DAYS PRIOR TO THE END
OF ANY TERM.

         LANDLORD MAY, AT LANDLORD'S ELECTION, GIVE TENANT WRITTEN NOTICE OF
LANDLORD'S ELECTION TO TERMINATE TENANCY NOT LESS THAN SIXTY (60) DAYS PRIOR TO
THE END OF ANY TERM, OR ELECT EARLY TERMINATION PURSUANT TO THE PROVISIONS OF
SECTION 3.1. NOTHING HEREIN SHALL BE DEEMED TO PROVIDE TENANT WITH AN
IRREVOCABLE OPTION TO RENEW TENANT'S TENANCY. EXPRESS RENEWAL AND AUTOMATIC
RENEWAL ARE EXPRESSLY CONDITIONED UPON LANDLORD'S CONSENT,

<PAGE>

WHICH SHALL BE DEEMED GIVEN ABSENT LANDLORD'S WRITTEN NOTICE OF TERMINATION OF
TENANCY.

         (a)      Upon termination or default of this Lease, Tenant agrees to
return to Landlord any equipment provided by Landlord to Tenant. The equipment
is, and shall remain at all times, the property of Landlord. Further, Tenant
shall provide Landlord with a forwarding address such that residual billings can
be mailed to Tenant.

         (b)      Tenant, including its principals, partners, shareholders,
officers, directors, managers, members, owners (collectively "Tenant's Related
Parties") and any parent, subsidiary or affiliated companies, jointly and
severally agree that during the term of this Lease or within one year following
the termination of this Lease, Tenant and Tenant's Related Parties will not hire
any of the employees of Landlord or persons employed by Landlord during the
90-day period prior to the hire date of said person by Tenant. In the event that
Tenant shall breach any obligation contained in this paragraph, Tenant shall be
liable to Landlord for, and shall pay to Landlord on demand, damages in the sum
of $5,000 for each such employee, it being mutually agreed by Tenant and
Landlord that this provision for liquidated damages is reasonable and that the
actual damage which would be sustained by Landlord as the result of a failure to
comply with the provisions would be impractical or extremely difficult to fix or
determine.

         212.     SURRENDER OF POSSESSION BY TENANT: Tenant hereby agrees, upon
the termination of this Lease, to immediately and peaceably yield up and
surrender the Premises in as good condition as the same were at the time of the
taking of possession, subject to reasonable wear and tear. Any personal property
remaining in the Premises upon expiration or termination shall be deemed
abandoned.

         Notwithstanding Tenant's failure to give 60 days notice of termination
as provided above, Landlord may, at any time prior to termination of the initial
term hereof or any 60 day renewal period, give Tenant a demand for possession of
the Premises upon termination of the initial term or the then applicable 60 day
period, as the case may be (the "Possession Date"). If Tenant remains in
possession of the premises after the Possession Date, Tenant shall become a
lessee at sufferance only, upon the same terms and conditions as contained
herein except that the monthly rent shall equal to two (2) times the monthly
rent which was in effect immediately prior to the Possession Date. Acceptance by
Landlord of rent after the Possession Date shall not constitute consent to a
holdover by Tenant or result in a renewal of this Lease. In addition, Tenant
shall indemnify and hold harmless Landlord and Landlord's Related Parties from
any and all claims, demands, losses or damages incurred by or asserted against
Landlord or Landlord's Related Parties due to Tenant's failure to deliver
possession of the Premises at the Possession Date including, without limitation,
any claims by any succeeding tenant for the Premises based on such delay.

         Without prior written consent, Tenant shall not remove any of
its/his/her property from the premises upon termination of this Lease, or at any
other time, except during Landlord's normal business hours. In the event that
Tenant elects to remove its property before or after normal business hours
following obtaining consent from Landlord, any expenses incurred by Landlord as
a result, including but not limited to additional expenses for security,
personnel, utilities and the like, shall be paid by Tenant.

<PAGE>

         223.     RIGHT OF ENTRY: Landlord's agent may enter upon the Premises
at any reasonable time to inspect and examine the Premises and to see that the
covenants hereof are being kept and performed, to take action which may be
required or permitted hereunder, to make such repairs, additions, or
improvements as Landlord shall deem necessary, or to exhibit the Premises to
prospective tenants or purchasers thereof.

         Landlord shall have the right to enter and show Tenant's office or
offices and related areas to prospective tenants during the sixty day period
after notice to vacate is received from Tenant.

         234.     SIGNS: Tenant shall not place or permit to be placed any sign,
advertisement, notice or other similar matter on any doors, windows, or walls or
other areas of the Premises which are open to the view of persons in the common
area of the ENCINO OFFICE PLAZA and/or EXECUTIVE SUITES or to persons outside of
the building in which the EXECUTIVE SUITES and the Premises are located.

         245.     KEYS: Two (2) keys to the Premises will be furnished by
Landlord. Additional keys will be furnished upon Tenant's payment to Landlord of
the fee therefore as determined by Landlord. Tenant shall not cause or permit
the duplication of any keys to be made, and Tenant shall not cause or permit any
keys to be possessed by any person other than an authorized agent of Tenant.
Tenant agrees to return to Landlord all keys to the Premises at the termination
of the tenancy. Landlord shall have the right to charge Tenant $25.00 for each
key which Tenant does not return to Landlord within five (5) days of vacating
the Premises.

         245.1.   SECURITY KEY FOBS: (When and if this system is intregrated.)
Security key fobs for electronic security system have been provided to Tenant in
the number set forth in the Basic Lease Terms. The security deposit collected
for each security key fob issued is $25.00. The charge for each lost security
key fob is $25.00. Tenant agrees to surrender each and every security key fob at
termination of tenancy and surrender of the Premises.

         256.     WAIVER: One or more waivers by Landlord of any breach of any
covenant or condition hereunder shall not be construed as a waiver of a
subsequent or continuing breach of the same or of any other covenant or
condition, and the consent or approval by Landlord to or of any act by Tenant
requiring Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent or approval to or of any subsequent act by
Tenant.

         267.     TIME OF THE ESSENCE: Time is expressly of the essence of this
Lease, and of all covenants and conditions contained herein.

         278.     SUCCESSORS AND ASSIGNS: The covenants and conditions herein
contained shall, subject to the provision as to assignments and subletting,
apply to and bind the heirs, successors, executors, administrators and assigns
of the respective parties hereto. If this Lease is executed by more than one
person as Tenant, their obligation shall be joint and several.

         289.     ATTORNEYS FEES: In the event of any legal action or proceeding
by Tenant or Landlord against the other under this Lease, the prevailing party
shall be

<PAGE>

entitled to recover all expenses and costs, including attorneys fees and costs
of appeal, if any, in such amount as is reasonable. In addition, should Landlord
retain legal counsel due to any default by Tenant, Tenant shall reimburse
Landlord its actual attorney fees and expenses incurred as a consequence of
remedying any default.

         2930.    NOTICES: All notices by Tenant or Landlord to the other must
be in writing. Notice to Tenant will be considered given if delivered personally
to Tenant or to one of Tenant's officers or mailed by registered or certified
mail, postage prepaid, addressed to Tenant, either at Landlord's premises
address described herein or at Tenant's address described herein. Notices to
Landlord will be considered given if mailed by registered or certified mail,
postage prepaid, to Landlord at Landlord's address set forth in the applicable
schedule or such other address as Landlord shall designate to Tenant in writing.

         301.     SEVERABILITY: The invalidity or unenforceability of any
provision hereof shall not affect or impair the validity or enforceability of
any other provision. No waiver of any default of Tenant shall be implied from
any failure by Landlord to take action with respect to such default.

         312.     ENTIRE AGREEMENT: This Lease supersedes any prior agreement or
agreements and embodies the entire agreement between Landlord and Tenant with
regard to the leasing of the Premises to Tenant, and may not be modified,
changed or altered in any way except in writing. Submission of this instrument
for examination does not constitute a reservation of or option for the Premises
and becomes effective only upon execution and delivery by both parties and shall
be interpreted and enforced in accordance with the laws of the State of
California.

         323.     AUTHORITY OF PARTIES AND GUARANTEE: Each party represents that
it has the full power and authority to enter into and perform this Lease. If
Tenant is a corporation or limited liability entity, each individual executing
this Lease on behalf of said corporation or limited liability entity represents
and warrants that he is duly authorized to execute and deliver this Lease on
behalf of said corporation or limited liability entity, and that this Lease is
binding on said corporation or limited liability entity.

         If Tenant is an unincorporated association or partnership, the
undersigned personally guarantees the full and faithful performance of the terms
and conditions of this Lease by the above Tenant in the event of default in the
performance, either under the remedies stated in the Lease, or those provided at
law.

         334.     HEADINGS: The section headings used in this Lease are intended
for convenience only and shall not be used in interpreting this Lease or in
determining any of the rights or obligations of the parties to this Lease.
