sublessee, upon receipt of a written notice from Lessor stating that a Breach

pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

     (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior Defaults

of thirty (30) days after written notice thereof by or on behalf of Lessor to
Lessee: provided, however, that if the nature of Lessee's Default is such that
more than thirty (30) days are reasonably required for its cure, then it shall

to provide Lessor with written alternative assurance or security, which, when
coupled with the then existing resources of Lessee, equals or exceeds the
combined financial resources of Lessee and the guarantors that existed at the
time of execution of this Lease, and such failure is a Breach.

     13.2 REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease and such failure is a Breach, Lessor may

<PAGE>   8

     (a) Terminate Lessee's right to possession of the Premises by any lawful
means, in which case this lease and the term hereof shall terminate and Lessee
shall immediately surrender possession of the Premises to Lessor. In such event
Lessor shall be entitled to recover from lessee: (i) the worth at the time of
the award of the unpaid rent which had been earned at the time of termination;
(ii) the worth at the time of award of the amount by which the unpaid rent which
would have been earned after termination until the time of award exceeds the
amount of such rental loss that the Lessee proves could have been reasonably
avoided; (iii) the worth at the time of award of the amount by which the unpaid
rent for the balance of the term after the time of award exceeds the amount of
such rental loss that the Lessee proves could be reasonably avoided; and (iv)
any other amount necessary to compensate Lessor for all the detriment
proximately caused by the Lessee'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 the cost of recovering possession of the
Premises, expenses of reletting, if allowed by law, reasonable attorneys' fees,
and that portion of the leasing commission paid by Lessor applicable to the
unexpired term of this Lease. The worth at the lime of award of the amount
referred to in provision (iii) of the prior sentence shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent. Efforts by Lessor to mitigate
damages caused by Lessee's Default or Breach of this Lease shall not waive
Lessor's right to recover damages under this Paragraph. If termination of this
Lease is obtained through the provisional remedy of unlawful detainer, Lessor
shall have the right to recover in such proceeding the unpaid rent and damages
as are recoverable therein, or Lessor may reserve therein the right to recover
all or any part thereof in a separate suit for such rent and/or damages. If a
notice and grace period required under subparagraphs 13.1(b), (c) or (d) was not
previously given, a notice to pay rent or quit, or to perform or quit, as the
case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by subparagraphs 13.11(b), (c) or (d). In such
case, the applicable grace period under subparagraphs 13.1(b), (c) or (d) and
under the unlawful detainer statute shall run concurrently after the one such
statutory notice, and the failure of Lessee to cure the Default within the
greater of the two such grace periods shall constitute both an unlawful detainer
and a Breach of this Lease entitling Lessor to the remedies provided for in this
lease and/or by said statute.

     (b) Continue the Lease and Lessee's right to possession in effect (in
California under California Civil Code Section 1951.1) after Lessee's Breach and
abandonment and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign, subject only to reasonable limitations. See
Paragraphs 12 and 36 for the limitations in assignment and subletting which
limitations Lessee and Lessor agree are reasonable. Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

     (c) Pursue any other remedy now or hereafter available to Lessor under the
laws or judicial decisions of the state wherein the Premises are located.

     (d) The expiration or termination of this Lease and/or the termination of
Lessee's right to possession shall not relieve Lessee from liability under any
indemnity provisions of this lease as to matters occurring or accruing during
the term hereof or by reason of Lessee's occupancy of the Premises.

     13.4 LATE CHARGES. Lessee hereby acknowledges that (ate payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within live (5) days after such
amount shall be due. then, without any requirement for notice to Lessee. Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
lessee. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 41 or any other provision of this Lease to the
contrary. Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be Performed by Lessor. For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than ten days or more than thirty (30) days after
receipt by Lessor, and by the holders of any ground lease, mortgage or deed of
trust covering the Premises whose name and address shall have been furnished
Lessee in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days after such
notice are reasonably required for its performance. Then Lessor shall not be in
breach of this lease if performance is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

14. CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threata exercise of said power (all of
which are herein called "condemnation"), this Lease shall terminate as to the
part so taken as of the date the condemning authority takes title or possession,
whichever first occurs. If more than ten percent (10%) of the floor area of the
Premises, or more than eighteen percent (18%) of the land area not occupied by
any building or property containing more than ten (10) parking spaces, is taken
by condemnation, Lessee may, at Lessee's option, to be exercised in writing
within ten (10) days after Lessor shall have given Lessee written notice of such
taking (or in the absence of such notice, within ten (10) days after the
condemning authority shall have taken possession) terminate this Lease as of the
date the condemning authority takes such possession. If Lessee does not
terminate this Lease in accordance with the foregoing, this Lease shall remain
in full force and effect as to the portion of the Premises remaining, except
that the Base Rent shall be reduced in the same proportion as the rentable floor
area of the Premises taken bears to the total rentable floor area of the budding
located on the Premises. No reduction of Base Rent shall occur if the only
portion of the Premises taken is land on which there is no building. Any award
for the taking of all or any part of the Premises under the power of eminent
domain or any payment made under threat of the exercise of such power shall be
the property of Lessor, whether such award shall be made as compensation for
diminution in value of the leasehold or for the taking of the fee, or as
severance damages; provided, however, that Lessee shell be entitled to any
compensation, awarded to Lessee for Lessee's relocation expenses and/or loss of
Lessee's Trade Fixtures. In the event that this Lease is not terminated by
reason of such condemnation, Lessor shall to the extent of its net severance
damages received, over and above the legal and other expenses incurred by Lessor
in the condemnation matter, repair any damage to the Premises caused by such
condemnation, except to the extent that Lessee has been reimbursed therefore by
the condemning authority. Lessee shall be responsible.

entity is entitled to any commission or finder's fee in connection with said
transaction. Lessee and Lessor do each hereby agree to indemnify, protect,
defend and hold the other harmless from and against liability for compensation

similar party by reason of any dealings or actions of the indemnifying Party,
including any costs, expenses, attorneys' fees reasonably incurred with respect
thereto.

transfer of Lessor's title or interest in the Premises or in this Lease. Lessor

of all liability with respect to the obligations and/or covenants under this
Lease thereafter to be performed by the Lessor. Subject to the foregoing, the
obligations and/or covenants in this Lease to be performed by the Lessor shall
be binding only upon the Lessor as hereinabove defined.

18. SEVERABILITY. The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

other than late charges, not received by Lessor within thirty (30) days
following the date on which it was due, shall bear interest from the
