2.       PREMISES.

         2.1      LETTING. Sublessor hereby subleases to Sublessee, and
Sublessee hereby subleases from Sublessor, the Premises, for the term, at the
rental, and upon all of the terms, covenants and conditions set forth in this
Sublease. Unless otherwise provided herein, any statement of size set forth in
this Sublease, or that may have been used in calculating Rent, is an
approximation which the Parties agree is reasonable and any payments based
thereon are not subject to revision whether or not the actual size is more or
less. NOTE: SUBLESSEE IS ADVISED TO VERIFY THE ACTUAL SIZE PRIOR TO EXECUTING
THIS SUBLEASE.

         2.2      CONDITION, See paragraph 18 of Addendum. Sublessor shall
deliver the Premises to Sublessee broom clean and free of debris on the
Commencement Date or the Early Possession Date, whichever first occurs ("Start
Date"), and warrants that the existing electrical, plumbing, fire sprinkler,
lighting, heating, ventilating and air conditioning systems ("HVAC"), and any
items which the Sublessor is obligated to construct pursuant to the Work Letter
attached hereto, if any, other than those constructed by Sublessee, shall be in
good operating condition on said date. If a non-compliance with such warranty
exists as of the Start Date, or if one of such systems or elements should
malfunction or fail within the appropriate warranty period, Sublessor shall, as
Sublessor's sole obligation with respect to such matter, except as otherwise
provided in this Sublease, promptly after receipt of written notice from
Sublessee setting forth with specificity the nature and extent of such
non-compliance, malfunction or failure, rectify same at Sublessor's expense. The
warranty periods shall be as follows: (i) 6 months as to the HVAC systems, and
(ii) 30 days as to the remaining systems and other elements. If Sublessee does
not give Sublessor the required notice within the appropriate warranty period,
correction of any such non-compliance, malfunction or failure shall be the
obligation of Sublessee at Sublessee's sole cost and expense

         2.3      COMPLIANCE. Sublessor warrants that any improvements,
alterations or utility installations made or installed by or on behalf of
Sublessor to or on the Premises comply with all applicable covenants or
restrictions of record and applicable building codes, regulations and ordinances
("APPLICABLE REQUIREMENTS") in effect on the date that they were made or
installed. Sublessor makes no warranty as to the use to which Sublessee will put
the Premises or to modifications which may be required by the Americans with
Disabilities Act or any similar laws as a result of Sublessee's use. NOTE:
SUBLESSEE IS RESPONSIBLE FOR DETERMINING WHETHER OR NOT THE ZONING AND OTHER
APPLICABLE REQUIREMENTS ARE APPROPRIATE FOR SUBLESSEE'S INTENDED USE, AND
ACKNOWLEDGES THAT PAST USES OF THE PREMISES MAY NO LONGER BE ALLOWED. If the
Premises do not comply with said warranty, Sublessor shall, except as otherwise
provided, promptly after receipt of written notice from Sublessee setting forth
with specificity the nature and extent of such non-compliance, rectify the same.
If the Applicable Requirements are hereafter changed so as to require during the
term of this Sublease the construction of an addition to or an alteration of the
Building, the remediation of any Hazardous Substance, or the reinforcement or
other physical modification of the Building ("Capital Expenditure"), Sublessor
and Sublessee shall allocate the cost of such work as follows:

                  (a)      If such Capital Expenditures are required as a result
of the specific and unique use of the Premises by Sublessee as compared with
uses by tenants in general, Sublessee shall be fully responsible for the cost
thereof, provided, however that if such Capital Expenditure is required during
the last two years of this Sublease and the cost thereof exceeds 6 months' Base
Rent, Sublessee may instead terminate this Sublease unless Sublessor notifies
Sublessee in writing, within 10 days after receipt of Sublessee's termination
notice that Sublessor has elected to pay the difference between the actual cost
thereof and the amount equal to 6 months' Base Rent. If the Parties elect
termination, Sublessee shall immediately cease the use of the Premises which
requires such Capital Expenditure and deliver to Sublessor written notice
specifying a termination date at least 90 days thereafter. Such termination date
shall, however, in no event be earlier than the last day that Sublessee could
legally utilize the Premises without commencing such Capital Expenditure.

                  (b)      If such Capital Expenditure is not the result of the
specific and unique use of the Premises by Sublessee (such as governmentally
mandated seismic modifications, then Sublessor shall pay for said Capital
Expenditure and the cost thereof shall be prorated between the Sublessor and
Sublessee and Sublessee shall only be obligated to pay, each month during the
remainder of the term of this Sublease, on the date on which Rent is due, an
amount equal to 1/144th the cost of such Capital Expenditure. Sublessee shall
pay interest on the unamortized balance at a rate that is then commercially
reasonable in the judgment of Sublessor's accountant. Sublessee may, however,
prepay its obligation at any time. Provided, however, that if such Capital
Expenditure is required during the last 2 years of this Sublease or if Sublessor
reasonably determines that it is not economically feasible to pay its share
thereof, Sublessor shall have the option to terminate this Sublease upon 90 days
prior written notice to Sublessee unless Sublessee notifies Sublessor, in
writing, within 10 days after receipt of Sublessor's termination notice that
Sublessee will pay for such Capital Expenditure. If Sublessor does not elect to
terminate, and fails to tender its share of any such Capital Expenditure,
Sublessee may advance such funds and deduct same, with interest, from Rent until
Sublessor's share of such costs have been fully paid. If Sublessee is unable to
finance Sublessor's share, or if the balance of the Rent due and payable for the
remainder of this Sublease is not sufficient to fully reimburse Sublessee on an
offset basis, Sublessee shall have the right to terminate this Sublease upon 10
days written notice to Sublessor.


                                  Page 2 of 7


                 (c) Notwithstanding the above, the provisions concerning
Capital Expenditures are intended to apply only to non-voluntary unexpected and
new Applicable Requirements. If the Capital Expenditures are instead triggered
by Sublessee as a result of an actual or proposed change in use, change in
intensity of use, or modification to the Premises then, and in that event,
Sublessee shall be fully responsible for the cost thereof, and Sublessee shall
not have any right to terminate this Sublease.

         2.4      ACKNOWLEDGEMENTS. Sublessee acknowledges that: (a) it has been
advised by Sublessor and/or Brokers to satisfy itself with respect to the
condition of the Premises (including but not limited to the electrical, HVAC and
fire sprinkler systems, security, environmental aspects, and compliance with
Applicable Requirements and the Americans with Disabilities Act), and their
suitability for Sublessee's intended use (b) Sublessee has made such
investigation as it deems necessary with reference to such matters and assumes
all responsibility therefor as the same relate to its occupancy of the Premises,
and (c) neither Sublessor, Sublessor's agents, nor Brokers have made any oral or
written representations or warranties with respect to said matters other than as
set forth in this Sublease. In addition, Sublessor acknowledges that: (i)
Brokers have made no representations, promises or warranties concerning
Sublessee's ability to honor the Sublease or suitability to occupy the Premises,
and (ii) it is Sublessor's sole responsibility to investigate the financial
capability and/or suitability of all proposed tenants.

         2.5      AMERICANS WITH DISABILITIES ACT. In the event that as a result
of Sublessee's use, or intended use, of the Premises the Americans with
Disabilities Act or any similar law requires modifications or the construction
or installation of improvements in or to the Premises, Building, Project and/or
Common Areas, the Parties agree that such modifications, construction or
improvements shall be made at: [ ] Sublessor's expense [X] Sublessee's expense.
Notwithstanding the Sublease shall not be responsible for costs associated with
compliance to Americans With Disabilities Act unless Sublessee applies for a
construction permit causing compliance to be reviewed.

3.       POSSESSION.

         3.1      Early Possession. See paragraph 14 of Addendum. If Sublessee
totally or partially occupies the Premises prior to Commencement Date, the
obligation to pay Base Rent shall be abated for the period of such early
possession. All other terms of this Sublease (including but not limited to the
obligations to pay Sublessee's Share of Common Area Operating Expenses, Real
Property Taxes and insurance premiums and to maintain the Premises) shall,
however, be in effect during such period. Any such early possession shall not
affect the Expiration Date.

         3.3      Sublessee Compliance. Sublessor shall not be required to
tender possession of the Premises to Sublessee until Sublessee complies with its
obligation to provide evidence of insurance. Pending delivery of such evidence,
Sublessee shall be required to perform all of its obligations under this
Sublease from and after the Start Date, including the payment of Rent,
notwithstanding Sublessor's election to withhold possession pending receipt of
such evidence of insurance. Further, if Sublessee is required to perform any
other conditions prior to or concurrent with the Start Date, the Start Date
shall occur but Sublessor may elect to withhold possession until such conditions
are satisfied.

4.       RENT AND OTHER CHARGES.

         4.1      Rent Defined. All monetary obligations of Sublessee to
Sublessor under the terms of this Sublease (except for the Security Deposit) are
deemed to be rent ("Rent"). Rent shall be payable in lawful money of the United
States to Sublessor at the address stated herein or to such other persons or at
such other places as Sublessor may designate in writing.

         4.2      Utilities. Sublessee shall pay for all water, gas, heat,
light, power, telephone, trash disposal and other utilities and services
supplied to the Premises, together with any taxes thereon.

5.       Security Deposit. See paragraph 16 of Addendum. Sublessee shall deposit
with Sublessor the sum specified in Paragraph 1.6(b) as security for Sublessee's
faithful performance of Sublessee's obligations hereunder. If Sublessee fails to
pay Rent or other charges due hereunder, or otherwise defaults with respect to
any provision of this Sublease, Sublessor may use, apply or retain all or any
portion of said deposit for the payment of any Rent or other charge in default
or for the payment of any other sum to which Sublessor may become obligated by
reason of Sublessee's default, or to compensate Sublessor for any loss or damage
which Sublessor may suffer thereby. If Sublessor so uses or applies all or any,
portion of said deposit, Sublessee shall within 10 days after written demand
therefore forward to Sublessor an amount sufficient to restore said Deposit to
the full amount provided for herein and Sublessee's failure to do so shall be a
material breach of this Sublease. Sublessor shall not be required to keep said
Deposit separate from its general accounts. If Sublessee performs all of
Sublessee's obligations hereunder, said Deposit, or so much thereof as has not
therefore been applied by Sublessor, shall be returned, without payment of
interest to Sublessee (or at Sublessor's option, to the last assignee, if any,
of Sublessee's interest hereunder) at the expiration of the term hereof, and
after Sublessee has vacated the Premises. No trust relationship is created
herein between Sublessor and Sublessee with respect to said Security Deposit.

6.       Agreed Use. The Premises shall be used and occupied only for General
office and related legal uses.

7.       Master Lease.

         7.1      Sublessor is the lessee of the Premises by virtue of a lease,
hereinafter the "MASTER LEASE", wherein West Coast Realty Investors, Inc.,
successor in interest to BRS-Tustin Safeguard Associates is the lessor,
hereinafter the "MASTER LESSOR".

         7.2      This Sublease is and shall be at all times subject and
subordinate to the Master Lease.

         7.3      The terms, conditions and respective obligations of Sublessor
and Sublessee to each other under this Sublease shall be the terms and
conditions of the Master Lease except for those provisions of the Master Lease
which are directly contradicted by this Sublease in which event the terms of
this Sublease document shall control over the Master Lease. Therefore, for the
purposes of this Sublease, wherever in the Master Lease the word "Lessor" is
used it shall be deemed to mean the Sublessor herein and wherever in the Master
Lease the word "Lessee" is used it shall be deemed to mean the Sublessee herein.

         7.4      During the term of this Sublease and for all periods
subsequent for obligations which have arisen prior to the termination of this
Sublease, Sublessee does hereby expressly assume and agree to perform and comply
with, for the benefit of Sublessor and Master Lessor, each and every obligation
of Sublessor under the Master Lease except for the following paragraphs which
are excluded therefrom:

See paragraph 18 of Sublease Addendum and of the Master Lease, Addendum
paragraphs 1 & 2; paragraph 4. Any bonus rent shall be retained by sublessee.

         7.5      The obligations that Sublessee has assumed under paragraph 7.4
hereof are hereinafter referred to as the "SUBLESSEE'S ASSUMED OBLIGATIONS". The
obligations that sublessee has not assumed under paragraph 7.4 hereof are
hereinafter referred to as the "SUBLESSOR'S REMAINING OBLIGATIONS".

         7.6      Sublessee shall hold Sublessor free and harmless from all
liability, judgments, costs, damages, claims or demands, including reasonable
attorneys fees, arising out of Sublessee's failure to comply with or perform
Sublessee's Assumed Obligations.

         7.7      Sublessor agrees to maintain the Master Lease during the
entire term of this Sublease, subject, however, to any earlier termination of
the Master Lease without the fault of the Sublessor, and to comply with or
perform Sublessor's Remaining Obligations and to hold Sublessee free and
harmless from all liability, judgments, costs, damages, claims or demands
arising out of Sublessor's failure to comply with or perform Sublessor's
Remaining Obligations.

         7.8      Sublessor represents to Sublessee that the Master Lease is in
full force and effect and that no default exists on the part of any Party to the
Master Lease.

8.       ASSIGNMENT OF SUBLEASE AND DEFAULT.

         8.1      Sublessor hereby assigns and transfers to Master Lessor
Sublessor's interest in this Sublease, subject however to the provisions of
Paragraph 8.2 hereof.

         8.2      Master Lessor, by executing this document, agrees that until a
Default shall occur in the performance of Sublessor's Obligations under the
Master Lease, that Sublessor may receive, collect and enjoy the Rent accruing
under this Sublease. However, if Sublessor shall Default in the performance of
its obligations to Master Lessor then Master Lessor may, at its option, receive
and collect, directly from Sublessee, all Rent owing and to be owed under this
Sublease. In the event, however, that the amount collected by Master Lessor
exceeds Sublessor's obligations any such excess shall be refunded to Sublessor.
Master Lessor shall not, by reason of this assignment of the Sublease nor by
reason of the collection of the Rent from the Sublessee, be deemed liable to
Sublessee for any failure of the Sublessor to perform and comply with
Sublessor's Remaining Obligations.

         8.3      Sublessor hereby irrevocably authorizes and directs Sublessee
upon receipt of any written notice from the Master Lessor stating that a Default
exists in the performance of Sublessor's obligations under the Master Lease, to
pay to Master Lessor the Rent due and to become due under the Sublease.
Sublessor agrees that Sublessee shall have the right to rely upon any such
statement and request from Master Lessor, and that Sublessee shall pay such Rent
to Master Lessor without any obligation or right to inquire as to whether such
Default exists and notwithstanding any notice from or claim from Sublessor to
the contrary and Sublessor shall have no right or claim against Sublessee for
any such Rent so paid by Sublessee.

         8.4      No changes or modifications shall be made to this Sublease
without the consent of Master Lessor.

9.       CONSENT OF MASTER LESSOR.

         9.1      In the event that the Master Lease requires that Sublessor
obtain the consent of Master Lessor to any subletting by Sublessor then, this
Sublease shall not be effective unless, within 10 days of the date hereof,
Master Lessor signs this Sublease thereby giving its consent to this Subletting.

         9.2      In the event that the obligations of the Sublessor under the
Master Lease have been guaranteed by third parties, then neither this Sublease,
nor the Master Lessor's consent, shall be effective unless, within 10 days of
the date hereof, said guarantors sign this Sublease thereby giving their consent
to this Sublease.

         9.3      In the event that Master Lessor does give such consent then:

                  (a)      Such consent shall not release Sublessor of its
obligations or alter the primary liability of Sublessor to pay the Rent and
perform and comply with all of the obligations of Sublessor to be performed
under the Master Lease.

                  (b)      The acceptance of Rent by Master Lessor from
Sublessee or any one else liable under the Master Lease shall not be deemed a
waiver by Master Lessor of any provisions of the Master Lease.

                  (c)      The consent to this Sublease shall not constitute a
consent to any subsequent subletting or assignment.

                  (d)      In the event of any Default of Sublessor under the
Master Lease, Master Lessor may proceed directly against Sublessor, any
guarantors or any one else liable under the Master Lease or this Sublease
without first exhausting Master Lessor's remedies against any other person or
entity liable thereon to Master Lessor.

                  (e)      Master Lessor may consent to subsequent sublettings
and assignments of the Master Lease or this Sublease or


                                  Page 4 of 7


any amendments or modifications thereto without notifying Sublessor or any one
else liable under the Master Lease and without obtaining their consent and such
action shall not relieve such persons from liability.

                  (f)      In the event that Sublessor shall Default in its
obligations under the Master Lease, then Master Lessor, at its option and
without being obligated to do so, may require Sublessee to attorn to Master
Lessor in which event Master Lessor shall undertake the obligations of Sublessor
under this Sublease from the time of the exercise of said option to termination
of this Sublease but Master Lessor shall not be liable for any prepaid Rent nor
any Security Deposit paid by Sublessee, nor shall Master Lessor be liable for
any other Defaults of the Sublessor under the Sublease.

                  (g)      Unless directly contradicted by other provisions of
this Sublease, the consent of Master Lessor to this Sublease shall not
constitute an agreement to allow Sublessee to exercise any options which may
have been granted to Sublessor in the Master Lease (see Paragraph 39.2 of the
Master Lease).

         9.4      The signatures of the Master Lessor and any Guarantors of
Sublessor at the end of this document shall constitute their consent to the
terms of this Sublease.

         9.5      Master Lessor acknowledges that, to the best of Master
Lessor's knowledge, no Default presently exists under the Master Lease of
obligations to be performed by Sublessor and that the Master Lease is in full
force and effect.

         9.6      In the event that Sublessor Defaults under its obligations to
be performed under the Master Lease by Sublessor, Master Lessor agrees to
deliver to Sublessee a copy of any such notice of default. Sublessee shall have
the right to cure any Default of Sublessor described in any notice of default
within ten days after service of such notice of default on Sublessee. If such
Default is cured by Sublessee then Sublessee shall have the right of
reimbursement and offset from and against Sublessor.

11.      REPRESENTATIONS AND INDEMNITIES OF BROKER RELATIONSHIPS. The Parties
each represent and warrant to the other that it has had no dealings with any
person, firm, broker or finder (other than the Brokers, if any) in connection
with this Sublease, and that no one other than said named Brokers is entitled to
any commission or finder's fee in connection herewith. Sublessee and Sublessor
do each hereby agree to indemnify, protect, defend and hold the other harmless
from and against liability for compensation or charges which may be claimed by
any such unnamed broker, finder or other similar party by reason of any dealings
or actions of the indemnifying Party, including any costs, expenses, attorneys'
fees reasonably incurred with respect thereto.

12.      ATTORNEY'S FEES. If any Party or Broker brings an action or proceeding
involving the Premises whether founded in tort, contract or equity, or to
declare rights hereunder, the Prevailing Party (as hereafter defined) in any
such proceeding, action, or appeal thereon, shall be entitled to reasonable
attorneys' fees. Such fees may be awarded in the same suit or recovered in a
separate suit, whether or not such action or proceeding is pursued to decision
or judgment. The term, "PREVAILING PARTY" shall include, without limitation, a
Party or Broker who substantially obtains or defeats the relief sought, as the
case may be, whether by compromise, settlement, judgment, or the abandonment by
the other Party or Broker of its claim or defense. The attorneys' fees award
shall not be computed in accordance with any court fee schedule, but shall be
such as to fully reimburse all attorneys' fees reasonably incurred. In addition,
Sublessor shall be entitled to attorneys' fees, costs and expenses incurred in
the preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting Breach ($200 is a reasonable minimum
per occurrence for such services and consultation).

13.      NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Sublease contains
all agreements between the Parties with respect to any matter mentioned herein,
and no other prior or contemporaneous agreement or understanding shall be
effective. Sublessor and Sublessee each represents and warrants to the Brokers
that it has made, and is relying solely upon, its own investigation as to the
nature, quality, character and financial responsibility of the other Party to
this Sublease and as to the use, nature, quality and character of the Premises.
Brokers have no responsibility with respect thereto or with respect to any
default or breach hereof by either Party. The liability (including court costs
and attorneys' fees), of any Broker with respect to negotiation, execution,
delivery or performance by either Sublessor or Sublessee under this Sublease or
any amendment or modification hereto shall be limited to an amount up to the fee
received by such Broker pursuant to this Sublease; provided, however, that the
foregoing limitation on each Broker's liability shall not be applicable to any
gross negligence or willful misconduct of such Broker.

14.      WITH THE EXCEPTION OF THE CONFERENCE ROOM TABLE & CHAIRS, SUBLESSEE
SHALL HAVE THE RIGHT TO USE THE FURNITURE NOW IN PLACE. SUBLESSEE'S RIGHTS TO
THE FURNITURE SHALL LAPSE UPON SUBLEASE TERMINATION.
