from Lessor, the Premises, for the term, at the rental, and upon all of the 
terms, covenants and conditions set forth in this Lease. Unless otherwise 
provided herein, any statement of square footage set forth in this Lease, or 
that may have been used in calculating rental, is an approximation which 
Lessor and Lessee agree is reasonable and the rental based thereon is not 
subject to revision whether or not the actual square footage is more or less.

    2.4  ACCEPTANCE OF PREMISES. Lessee hereby acknowledges: (a) that it has 
been advised by the Brokers to satisfy itself with respect to the condition 
of the Premises (including but not limited to the electrical and fire 
sprinkler systems, security, environmental aspects, compliance with 
Applicable Law as defined in Paragraph 6.3) and the present and future 
suitability of the Premises for Lessee's intended use, (b) that Lessee has 
made such investigation as it deems necessary with reference to such matters 
and assumes all responsibility therefor as the same relate to Lessee's 
occupancy of the Premises and/or the term of this Lease, and (c) that neither 
Lessor, nor any of Lessor's agents, has made any oral or written 
representations or warranties with respect to the said matters other than as 
set forth in this Lease.

    2.5  LESSEE PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this 
Paragraph 2 shall be of no force or effect if immediately prior to the date set 
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In 
such event, Lessee shall, at Lessee's sole cost and expense, correct any 
non-compliance of the Premises with said warranties.

3.  TERM.

    3.1  TERM. The Commencement Date, Expiration Date and Original Term of 
this Lease are as specified in Paragraph 1.3.



    3.3  DELAY IN POSSESSION. If for any reason Lessor cannot deliver 
possession of the Premises to Lessee as agreed herein by the Early Possession 
Date, if one is specified in Paragraph 1.4, or, if no Early Possession Date 
is specified, by the Commencement Date, Lessor shall not be subject to any 
liability therefor, nor shall such failure affect the validity of this Lease, 
or the obligations of Lessee hereunder, or extend the term hereof, but in 
such case, Lessee shall not, except as otherwise provided herein, be 
obligated to pay rent or perform any other obligation of Lessee under the 
terms of this Lease until Lessor delivers possession of the Premises to 
Lessee.

4.  RENT.

    4.1  BASE RENT. Except as herein provided, Lessee shall cause payment of 
Base Rent and other rent or charges, as the same may be adjusted from time to 
time, to be received by Lessor in lawful money of the United States, without 
abatement, offset or deduction, on or before the day on which it is due under 
the terms of this Lease. Base Rent and all other rent and charges for any 
period during the term hereof which is for less than one (1) full calendar 
month shall be prorated based upon the actual number of days of the calendar 
month involved. Payment of Base Rent and other charges shall be made to 
Lessor at its address stated herein or to such other persons or at such other 
addresses as Lessor may from time to time designate in writing to Lessee.

5.  SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof 
the Security Deposit set forth in Paragraph 1.7 as security for Lessee's 
faithful performance of Lessee's obligations under this Lease. If Lessee 
fails to pay Base Rent or other rent or charges due hereunder, or otherwise 
Defaults under this Lease (as defined in Paragraph 13.1), Lessor may use, 
apply or retain all or any portion of said Security Deposit for the payment 
of any amount due Lessor or to reimburse or compensate Lessor for any 
liability, cost, expense, loss or damage (including attorneys' fees) which 
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all 
or any portion of said Security Deposit, Lessee shall within ten (10) days 
after written request therefor deposit moneys with Lessor sufficient to 
restore said Security Deposit to the full amount required by this Lease. Any 
time the Base Rent increases during the term of this Lease, Lessee shall, 
upon written request from Lessor, deposit additional moneys with Lessor 
sufficient to maintain the same ratio between the Security Deposit and the 
Base Rent as those amounts are specified in the Basic Provisions. Lessor 
shall not be required to keep all or any part of the Security Deposit 
separate from its general accounts. Lessor shall, at the expiration or 
earlier termination of the term hereof and after Lessee has vacated the 
Premises, return to Lessee (or, at Lessor's option, to the last assignee, if 
any, of Lessee's interest herein), that portion of the Security Deposit not 
used or applied by Lessor. Unless otherwise expressly agreed in writing by 
Lessor, no part of the Security Deposit shall be considered to be held in 
trust, to bear interest or other increment for its use, or to be prepayment 
for any moneys to be paid by Lessee under this Lease.

6.  USE.

    6.1  USE. Lessee shall use and occupy the Premises only for the purposes 
set forth in Paragraph 1.8, or any other use which is comparable thereto, and 
for no other purpose. Lessee shall not use or permit the use of the Premises 
in a manner that creates waste or a nuisance, or that disturbs owners and/or 
occupants of, or causes damage to, neighboring premises or properties.

    6.2  HAZARDOUS SUBSTANCES.

         (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS SUBSTANCE" 
as used in this Lease shall mean any product, substance, chemical, material 
or waste whose presence, nature, quantity and/or intensity of existence, use, 
manufacture, disposal, transportation, spill, release or effect, either by 
itself or in combination with other materials expected to be on the Premises, 
is either: (i) potentially injurious to the public health, safety or welfare, 
the environment or the Premises, (ii) regulated or monitored by any 
governmental authority, or (iii) a basis for liability of Lessor to any 
governmental agency or third party under any applicable statute or common law 
theory. Hazardous Substance shall include, but not be limited to, 
hydrocarbons, petroleum, gasoline, crude oil or any products, by-products or 
fractions thereof. Lessee shall not engage in any activity in, on or about 
the Premises which constitutes a Reportable Use (as hereinafter defined) of 
Hazardous Substances without the express prior written consent of Lessor, and 
compliance in a timely manner (at Lessee's sole cost and expense) with all 
Applicable Law (as defined in Paragraph 6.3). "REPORTABLE USE" shall mean (i) 
the installation or use of any above or below ground storage tank, (ii) the 
generation, possession, storage, use, transportation, or disposal of a 
Hazardous Substance that requires a permit from, or with respect to which a 
report, notice, registration or business plan is required to be filed with, 
any governmental authority. Reportable Use shall also include Lessee's being 
responsible for the presence in, on or about the Premises of a Hazardous 
Substance with respect to which any Applicable Law requires that a notice be 
given to persons entering or occupying the Premises or neighboring 
properties. Notwithstanding the foregoing, Lessee may, without Lessor's prior 
consent, but in compliance with all Applicable Laws, use any ordinary and 
customary materials reasonably required to be used by Lessee in the normal 
course of Lessee's business permitted on the Premises, so long as such use is 
not a Reportable Use and does not expose the Premises or neighboring 
properties to any meaningful risk of contamination or damage or expose Lessor 
to any liability therefor. In addition, Lessor may (but without any 
obligation to do so) condition its consent to the use or presence of any 
Hazardous Substance, activity or storage tank by Lessee upon Lessee's giving 
Lessor such additional assurances as Lessor, in its reasonable discretion, 
deems necessary to protect itself, the public, the Premises and the 
environment against damage, contamination or injury and/or liability 
therefrom or therefor, including, but not limited to, the installation (and 
removal on or before Lease expiration or earlier termination) of reasonably 
necessary protective modifications to the Premises (such as concrete 
encasements) and/or the deposit of an additional Security Deposit under 
Paragraph 8 hereof.

         (b) DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause 
to believe, that a Hazardous Substance, or a condition involving or resulting 
from same, has come to be located in, on, under or about the Premises, other 
than as previously consented to by Lessor, Lessee shall immediately give 
written notice of such fact to Lessor. Lessee shall also immediately give 
Lessor a copy of any statement, report, notice, registration, application, 
permit, business plan, license, claim, action or proceeding given to, or 
received from, any governmental authority or private party, or persons 
entering or occupying the Premises, concerning the presence, spill, release, 
discharge of, or exposure to, any Hazardous Substance or contamination in, 
on, or about the Premises, including but not limited to all such documents as 
may be involved in any Reportable Uses involving the Premises.

         (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and 
hold Lessor, its agents, employees, lenders and ground lessor, if any, and 
the Premises, harmless from and against any and all loss of rents and/or 
damages, liabilities, judgments, costs, claims, liens, expenses, penalties, 
permits and attorney's and consultant's fees arising out of or involving any 
Hazardous Substance or storage tank brought onto the Premises by or for 
Lessee or under Lessee's control. Lessee's obligations under this Paragraph 6 
shall include, but not be limited to, the effects of any contamination or 
injury to person, property or the environment created or suffered by Lessee, 
and the cost of investigation (including consultant's and attorney's fees and 
testing), removal, remediation, restoration and/or abatement thereof, or of 
any contamination therein involved, and shall survive the expiration or 
earlier termination of this Lease. No termination, cancellation or release 
agreement entered into by Lessor and Lessee shall release Lessee from its 
obligations under this Lease with respect to Hazardous Substances or storage 
tanks, unless specifically so agreed by Lessor in writing at the time of such 
agreement.

    6.3  LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this 
Lease, Lessee, shall, at Lessee's sole cost and expense, fully, diligently 
and in a timely manner, comply with all "APPLICABLE LAW," which term is used 
in this Lease to include all laws, rules, regulations, ordinances, 
directives, covenants, easements and restrictions of record, permits, the 
requirements of any applicable fire insurance underwriter or rating bureau, 
and the recommendations of Lessor's engineers and/or consultants, relating in 
any manner to the Premises (including but not limited to matters pertaining 
to (i) industrial hygiene, (ii) environmental conditions on, in, under or 
about the Premises, including soil and groundwater conditions, and (iii) the 
use, generation, manufacture, production, installation, maintenance, removal, 
transportation, storage, spill or release of any Hazardous Substance or 
storage tank), now in effect or which may hereafter come into effect, and 
whether or not reflecting a change in policy from any previously existing 
policy. Lessee shall, within five (5) days after receipt of Lessor's written 
request, provide Lessor with copies of all documents and information, 
including, but not limited to, permits, registrations, manifests, 
applications, reports and certificates, evidencing Lessee's compliance with 
any Applicable Law specified by Lessor, and shall immediately upon receipt, 
notify Lessor in writing (with copies of any documents involved) of any 
threatened or actual claim, notice, citation, warning, complaint or report 
pertaining to or involving failure by Lessee or the Premises to comply with 
any Applicable Law.

    6.4  INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined in 
Paragraph 8.3(a)) shall have the right to enter the Premises at any time, in 
the case of an emergency, and otherwise at reasonable times, for the purpose 
of inspecting the condition of the Premises and for verifying compliance by 
Lessee with this Lease and all Applicable Laws (as defined in Paragraph 6.3), 
and to employ experts and/or consultants in connection therewith and/or to 
advise Lessor with respect to Lessee's activities, including but not limited 
to the installation, operation, use, monitoring, maintenance, or removal of 
any Hazardous Substance or storage tank on or from the Premises. The costs 
and expenses of any such inspections shall be paid by the party requesting 
same, unless a Default or Breach of this Lease, violation of Applicable Law, 
or a contamination, caused or materially contributed to by Lessee is found to 
exist or be imminent, or unless the inspection is requested or ordered by a 
governmental authority as the result of any such existing or imminent 
violation or contamination. In any such case, Lessee shall upon request 
reimburse Lessor or Lessor's Lender, as the case may be, for the costs and 
expenses of such inspections.

7.  MAINTENANCE; REPAIRS; UTILITY INSTALLATIONS; TRADE FIXTURES AND 
    ALTERATIONS.

    7.1  LESSEE'S OBLIGATIONS.

         (a) Subject to the provisions of Paragraphs 2.2. (Lessor's warranty 
as to condition), 2.3 (Lessor's warranty as to compliance with covenants, 
etc.) 7.2 (Lessor's obligations to repair), 9 (damage and destruction), and 
14 (condemnation), Lessee shall, at Lessee's sole cost and expense and at all 
times, keep the Premises and every part thereof in good order, condition and 
repair, structural and non-structural (whether or not such portion of the 
Premises requiring repair, or the means of repairing the same, are reasonably 
or readily accessible to Lessee, and whether or not the need for such repairs 
occurs





as a result of Lessee's use, any prior use, the elements or the age of such 
portion of the Premises), including, without limiting the generality of the 
foregoing all equipment or facilities serving the Premises, such as plumbing, 
heating, air conditioning, ventilating, electrical, lighting facilities, 
boilers, fired or unfired pressure vessels, fire sprinkler and/or standpipe 
and hose or other automatic fire extinguishing system, including fire alarm 
and/or smoke detection systems and equipment, fire hydrants, fixtures, walls 
(interior and exterior), foundations, ceilings, roofs, floors, windows, 
doors, plate glass, skylight, landscaping, driveways, parking lots, fences, 
retaining walls, signs, sidewalks and parkways located in, on, about, or 
adjacent to the Premises. Lessees shall not cause or permit any Hazardous 
Substance to be spilled or released in, on, under or about the Premises 
(including through the plumbing or sanitary sewer system) and shall promptly, 
at Lessee's expense, take all investigatory and/or remedial action reasonably 
recommended, whether or not formally ordered or required, for the cleanup of 
any contamination of, and for the maintenance, security and/or monitoring of 
the Premises, the elements surrounding same, or neighboring properties, that 
was caused or materially contributed to by Lessee, or pertaining to or 
involving any Hazardous Substance and/or storage tank brought onto the 
Premises by or for Lessee or under its control. Lessee, in keeping the 
Premises in good order, condition and repair, shall exercise and perform good 
maintenance practices. Lessee's obligations shall include restorations, 
replacements or renewals when necessary to keep the Premises and all 
improvements thereon or a part thereof in good order, condition and state of 
repair. If Lessee occupies the Premises for seven (7) years or more, Lessor 
may require Lessee to repaint the exterior of the buildings on the Premises 
as reasonably required, but not more frequently than once every seven (7) 
years.

     (b) Lessee shall, at Lessee's sole cost and expense, procure and 
maintain contracts, with copies to Lessor, in customary form and substance 
for, and with contractors specializing and experienced in, the inspection, 
maintenance and service of the following equipment and improvements, if any, 
located on the Premises: (i) heating, air conditioning and ventilation 
equipment, (ii) boiler, fired or unfired pressure vessels, (iii) fire 
sprinkler and/or standpipe and hose or other automatic fire extinguishing 
systems, including fire alarm and/or smoke detection, (iv) landscaping and 
irrigation system, (v) roof covering and drain maintenance and (vi) asphalt

   7.2 LESSOR'S OBLIGATIONS. It is intended by the Parties hereto that Lessor 
have no obligation, in any manner whatsoever, to repair and maintain the 
Premises the improvements located thereon, or the equipment therein, whether 
structural or non structural, all of which obligations are intended to be 
that of the Lessee under Paragraph 7.1 hereof. It is the intention of the 
Parties that the terms of this Lease govern the respective obligations of the 
Parties as to maintenance and repair of the Premises. Lessee and Lessor 
expressly waive the benefit of any statute now or hereafter in effect to the 
extent it is inconsistent with the terms of this Lease with respect to, or 
which affords Lessee the right to make repairs at the expense of Lessor or to 
terminate this Lease by reason of any needed repairs.

   7.3 UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

     (a) DEFINITIONS; CONSENT REQUIRED. The term "Utility Installations" is 
used in this Lease to refer to all carpeting, window coverings, air lines, 
power panels, electrical distribution, security, fire protection systems, 
communication systems, lighting fixtures, heating, ventilating, and air 
conditioning equipment, plumbing, and fencing in, on or about the Premises. 
The term "Trade Fixtures" shall mean Lessee's machinery and equipment that 
can be removed without doing material damage to the Premises. The term 
"Alterations" shall mean any modification of the improvements on the Premises 
from that which are provided by Lessor under the terms of this Lease, other 
than Utility Installations or Trade Fixtures, whether by addition or 
deletion. "Lessee Owned Alterations and/or Utility Installations" are defined 
as Alterations and/or Utility Installations made by Lessee that are not yet 
owned by Lessor as defined in Paragraph 7.4(a). Lessee shall not make any 
Alterations or Utility Installations in, on, under or about the Premises 
without Lessor's prior written consent. Lessee may, however, make 
non-structural Utility Installations to the interior of the Premises 
(excluding the roof), as long as they are not visible from the outside, do 
not involve puncturing, relocating or removing the roof or any existing 
walls, and the cumulative cost thereof during the term of this Lease as 
extended does not exceed $25,000, provided Lessee furnishes Lessor with plans 
and specifications and all other items specified in Paragraph 7.3(b).

     (b) CONSENT. Any Alterations or Utility Installations that Lessee shall 
desire to make and which require the consent of the Lessor shall be presented 
to Lessor in written form with proposed detailed plans. All consents given by 
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific 
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all 
applicable permits required by governmental authorities, (ii) the furnishing 
of copies of such permits together with a copy of the plans and 
specifications for the Alteration or Utility Installation to Lessor prior to 
commencement of the work thereon, and (iii) the compliance by Lessee with all 
conditions of said permits in a prompt and expeditious manner. Any 
Alterations or Utility Installations by Lessee during the term of this Lease 
shall be done in a good and workmanlike manner, with good and sufficient 
materials, and in compliance with all Applicable Law. Lessee shall promptly 
upon completion thereof furnish Lessor with as-built plans and specifications 
therefor. Lessor may (but without obligation to do so) condition its consent 
to any requested Alteration or Utility Installation that costs $10,000 or 
more upon Lessee's providing Lessor with a lien and completion bond in an 
amount equal to one and one-half times the estimated cost of such Alteration 
or Utility Installation and/or upon Lessee's posting an additional Security 
Deposit with Lessor under Paragraph 36 hereof.

     (c) INDEMNIFICATION. Lessee shall pay, when due, all claims for labor or 
materials furnished or alleged to have been furnished to or for Lessee at or 
for use on the Premises, which claims are or may be secured by any mechanics' 
or materialman's lien against the Premises or any interest therein. Lessee 
shall give Lessor not less than ten (10) days written notice prior to the 
commencement of any work in, on or about the Premises, and Lessor shall have 
the right to post notices of non-responsibility in or on the Premises as 
provided by law. If Lessee shall, in good faith, contest the validity of any 
such lien, claim or demand. Then Lessee shall, at its sole expense defend and 
protect itself, Lessor and the Premises against the same and shall pay and 
satisfy any such adverse judgment that may be rendered thereon before the 
enforcement thereof against the Lessor or the Premises. If Lessor shall 
require, Lessee shall furnish to Lessor a surety bond satisfactory to Lessor 
in an amount equal to one and one-half times the amount of such contested 
lien, claim or demand indemnifying Lessor against liability for the same, as 
required by law for the holding of the Premises free from the effect of such 
lien or claim. In addition, Lessor may require Lessee to pay Lessor's 
attorney's fees and costs in participating in such action if Lessor shall 
decide it is to its best interest to do so.

  7.4 OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

     (a) OWNERSHIP. Subject to Lessor's right to require their removal or 
become the owner thereof as hereinafter provided in this Paragraph 7.4 all 
Alterations and Utility Additions made to the Premises by Lessee shall be the 
property of and owned by Lessee, but considered a part of the Premises. Lessor
may, at any time and at its option, elect in writing to Lessee to be the 
owner of all or any specified part of the Lessee Owned Alterations and 
Utility Installations. Unless otherwise instructed per subparagraph 7.4(b) 
hereof, all Lessee Owned Alterations and Utility Installations shall, at the 
expiration or earlier termination of this Lease, become the property of 
Lessor and remain upon and be surrendered by Lessee with the Premises.

     (b) REMOVAL. Unless otherwise agreed in writing, Lessor may require that 
any or all Lessee Owned Alterations or Utility Installations be removed by 
the expiration or earlier termination of this Lease, notwithstanding their 
installation may have been consented to by Lessor. Lessor may require the 
removal at any time of all or any part of any Lessee Owned Alterations or 
Utility Installations made without the required consent of Lessor.

     (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by the 
end of the last day of the Lessee term or any earlier termination date, with 
all of the improvements, parts and surfaces thereof clean and free of debris 
and in good operating order, condition and state of repair, ordinary wear and 
tear excepted. "Ordinary wear and tear" shall not include any damage or 
deterioration that would have been prevented by good maintenance practice or 
by Lessee performing all of its obligations under this Lease. Except as 
otherwise agreed or specified in writing by Lessor, the Premises, as 
surrendered, shall include the Utility Installations. The obligation of 
Lessee shall include the repair of any damage occasioned by the installation, 
maintenance or removal of Lessee's Trade Fixtures, furnishings, equipment, 
and Alterations and/or Utility Installations, as well as the removal of any 
storage tank installed by or for Lessee, and the removal, replacement, or 
remediation of any soil, material or ground water contaminated by Lessee, all 
as may then be required by Applicable Law and/or good practice. Lessee's 
Trade Fixtures shall remain the property of Lessee and shall be removed by 
Lessee subject to its obligation to repair and restore the Premises per this 
Lease.

8. INSURANCE: INDEMNITY.

   8.1 PAYMENT FOR INSURANCE. Regardless of whether the Lessor or Lessee is 
the insuring Party, Lessee shall pay for all insurance required under this
Paragraph 8 except to the extent of the cost attributable to liability 
insurance carried by Lessor in excess of $3,000,000 per occurrence. Premiums 
for policy periods commencing prior to or extending beyond the Lease term 
shall be prorated to correspond to the Lease term. Payment shall be made by 
Lessee to Lessor within ten (10) days following receipt of an invoice for any 
amount due.

   8.2 LIABILITY INSURANCE.

     (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force during the 
term of this Lease a Commercial General Liability policy of insurance 
protecting Lessee and Lessor (as an additional insured) against claims for 
bodily injury, personal injury and property damage based upon, involving or 
arising out of the ownership, use, occupancy or maintenance of the Premises 
and all areas appurtenant thereto. Such insurance shall be on an occurrence 
basis providing single limit coverage in an amount not less than $3,000,000 
per occurrence with an "Additional insured Managers or Lessors of 
Premises Endorsement and contain the "Amendment of the Pollution Exclusion" 
for damage caused by heat, smoke or fumes from a hostile fire. The policy 
shall not contain any intra-insured exclusions as between insured persons 
or organizations, but shall include coverage for liability assumed under this 
Lease as an "insured contract" for the performance of Lessee's indemnity 
obligations under this Lease. The limits of said insurance required by this 
Lease or as carried by Lessee shall not, however, limit the liability of 
Lessee nor relieve Lessee of any obligation hereunder. All insurance to be 
carried by Lessee shall be primary to and not contributory with any similar 
insurance carried by Lessor, whose insurance shall be considered excess 
insurance only.

     (b) CARRIED BY LESSOR. In the event Lessor is the Insuring Party, Lessor 
shall also maintain liability insurance described in Paragraph 8.2(a) above. 
In addition to, and not in lieu of, the insurance required to be maintained by 
Lessee. Lessee shall not be named as an additional insured therein.

   8.3 PROPERTY INSURANCE--BUILDING, IMPROVEMENTS AND RENTAL VALUE.

      (a) BUILDING AND IMPROVEMENTS. The Insuring Party shall obtain and keep 
in force during the term of this Lease a policy or policies in the name of 
Lessor with loss payable to Lessor and to the holders of any mortgages, deeds 
of trust or ground leases on the Premises ("Lender(s)"), insuring loss

                                                      


or damage to the Premises. The amount of such insurance shall be equal to the 
full replacement cost of the Premises, as the same shall exist from time to 
time, or the amount required by Lenders, but in no event more than the 
commercially reasonable and available insurable value thereof if, by reason 
of the unique nature or age of the improvements involved, such latter amount 
is less than full replacement cost. If Lessor is the Insuring Party, however, 
Lessee Owned Alterations and Utility Installations shall be insured by 
Lessee under Paragraph 8.4 rather than by Lessor. If the coverage is available 
and commercially appropriate, such policy or policies shall insure against 
all risks of direct physical loss or damage (except the perils of flood 
and/or earthquake unless required by a Lender), including coverage for any 
additional costs resulting from debris removal and reasonable amounts of 
coverage for the enforcement of any ordinance or law regulating the 
reconstruction or replacement of any undamaged sections of the Premises 
required to be demolished or removed by reason of the enforcement of any 
building, zoning, safety or land use laws as the result of a covered cause 
of loss. Said policy or policies shall also contain an agreed valuation 
provision in lieu of any coinsurance clause, waiver of subrogation, and 
inflation guard protection causing an increase in the annual property 
insurance coverage amount by a factor of not less than the adjusted U.S. 
Department of Labor Consumer Price Index for All Urban Consumers for the city 
nearest to where the Premises are located. If such insurance coverage has a 
deductible clause, the deductible amount shall not exceed $1,000 per 
occurrence, and Lessee shall be liable for such deductible amount in the 
event of an Insured Loss, as defined in Paragraph 9.1(c).

any scheduled rental increases). Said insurance shall provide that in the 
event the Lease is terminated by reason of an insured loss, the period of 
indemnity for such coverage shall be extended beyond the date of the

building, or if the Premises are part of a group of buildings owned by Lessor 
which are adjacent to the Premises, the Lessee shall pay for any increase in 
the premiums for the property insurance of such building or buildings if said 
increase is caused by Lessee's acts, omissions, use or occupancy of the 
Premises.

Lessor shall not be required to insure Lessee Owned Alterations and Utility 
Installations unless the item in question has become the property of Lessor

carried by Lessee under this Paragraph 8.3 shall insure Lessee Owned 
Alterations and Utility Installations.

     8.4 LESSEE'S PROPERTY INSURANCE. Subject to the requirements of

used by Lessee for the replacement of personal property or the restoration of 
Lessee Owned Alterations and Utility Installations. Lessee shall be the 
Insuring Party with respect to the insurance required by this Paragraph 8.4 
and shall provide Lessor with written evidence that such insurance is in

anything which shall invalidate the insurance policies referred to in this 
Paragraph 8. If Lessee is the Insuring Party, Lessee shall cause to be

fail to procure and maintain the insurance required to be carried by the 
Insuring Party under this Paragraph 8, the other Party may but shall not be 
required to, procure and maintain the same, but at Lessee's expense.

9. DAMAGE OR DESTRUCTION

      9.1 DEFINITIONS.

         (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to 
the improvements on the Premises, other than Lessee Owned Alterations and 
Utility Installations, the repair cost of which damage or destruction is less 
than 50% of the then Replacement Cost of the Premises immediately prior to 
such damage or destruction, excluding from such calculation the value of the 
land and Lessee Owned Alterations and Utility Installations.

         (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction to
the Premises, other than Lessee Owned Alterations and Utility installations 
the repair cost of which damage or destruction is 50% or more of the then 
Replacement Cost of the Premises immediately prior to such damage or 
destruction, excluding from such calculation the value of the land and Lessee 
Owned Alterations and Utility Installations.

         (c) "INSURED LOSS" shall mean damage or destruction to improvements 
on the Premises, other than Lessee Owned Alterations and Utility 
Installations, which was caused by an event required to be covered by the 
insurance described in Paragraph 8.3(a), irrespective of any deductible 
amounts or coverage limits involved.

         (d) "REPLACEMENT COST" shall mean the cost to repair or rebuild the 
improvements owned by Lessor at the time of the occurrence to their condition 
existing immediately prior thereto, including demolition, debris removal and 
upgrading required by the operation of applicable building codes, ordinances 
or laws, and without deduction for depreciation.

         (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or 
discovery of a condition involving the presence of, or a contamination by a 
Hazardous Substance as defined in Paragraph 6.2(a), in , on, or under the 
Premises.

      9.2 PARTIAL DAMAGE--INSURED LOSS. If a Premises Partial Damage occurs, 
then Lessee shall, at Lessee's expense, repair such damage (but not Lessee's 
Trade Fixtures or Lessee Owned Alterations and Utility Installations) as soon 
as reasonably possible and this Lease shall continue in full force and 
effect; provided, however, that Lessee shall, at Lessor's election, make the 
repair of any damage or destruction the total cost to repair of which 
is $10,000 or less, and, in such event, Lessor shall make the insurance 
proceeds available to Lessee on a reasonable basis for that purpose 
Notwithstanding the foregoing, if the required insurance was not in force or 
the insurance proceeds are not sufficient to effect such repair, the insuring 
Party shall promptly contribute the shortage in proceeds (except as to the 
deductible which is Lessee's responsibility) as and when required to complete 
said repairs. In the event, however, the shortage in proceeds was due to the 
fact that, by reason of the unique nature of the improvements, full replacement
cost insurance coverage was not commercially reasonable and available. Lessor 
shall have no obligation to pay for the shortage in insurance proceeds or to 
fully restore the unique aspects of the Premises unless Lessee provides Lessor 
with the funds to cover same, or adequate assurance thereof within ten (10) 
days following receipt of written notice of such shortage and request therefor.
If Lessor receives said funds or adequate assurance thereof within said ten 
(10) day period, the party responsible for making the repairs shall complete 
them as soon as reasonably possible and this Lease shall remain in full force 
and effect. If Lessor does not receive such funds or assurance within said 
period, Lessor may nevertheless elect by written notice to Lessee within ten 
(10) days thereafter to make such restoration and repair as is commercially 
reasonable with Lessor paying any shortage in proceeds, in which case this 
Lease shall remain in full force and effect. If in such case Lessor does not 
so elect, then this Lease shall terminate sixty (60) days following the 
occurrence of the damage or destruction. Unless otherwise agreed, Lessee shall 
in no event have any right to reimbursement from Lessor for any funds 
contributed by Lessee to repair any such damage or destruction. Premises 
Partial Damage due to flood or earthquake shall be subject to Paragraph 9.3 
rather than Paragraph 9.2 notwithstanding that there may be some insurance 
coverage, but the net proceeds of any such insurance shall be made available 
for the repairs made by either Party.




   9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a 
Premises Total Destruction occurs (including any destruction required by any 
authorized public authority), this Lease shall terminate sixty (60) days 
following the date of such Premises Total Destruction, whether or not the 
damage or destruction is an insured Loss or was caused by a negligent or 
willful act of Lessee. In the event, however, that the damage or destruction 
was caused by Lessee, Lessor shall have the right to recover Lessor's damages 
from Lessee except as released and waived in Paragraph 8.6.

   9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6) months 
of the term of this Lease there is damage for which the cost to repair 
exceeds one (1) month's Base Rent, whether or not an insured Loss, Lessor 
may, at Lessor's option, terminate this Lease effective (60) days following 
the date of occurrence of such damage by giving written notice to Lessee of 
Lessor's election to do so within thirty (30) days after the date of 
occurrence of such damage. Provided, however, if Lessee at that time has an 
exercisable option to extend this Lease or to purchase the Premises, then 
Lessee may preserve this Lease by, within twenty (20) days following the 
occurrence of the damage, or before the expiration of the time provided in 
such option for its exercise, whichever is earlier ("Exercise Period"), (i) 
exercising such option and (ii) providing Lessor with any shortage in 
insurance proceeds (or adequate assurance thereof) needed to make the 
repairs. If Lessee duly exercises such option during said Exercise Period and 
provides Lessor with funds (or adequate assurance thereof) to cover any 
shortage in insurance proceeds, Lessor shall, at Lessor's expense repair such 
damage as soon as reasonably possible and this Lease shall continue in full 
force and effect. If Lessee fails to exercise such option and provide such 
funds or assurance during said Exercise Period, then Lessor may at Lessor's 
option terminate this Lease as of the expiration of said sixty (60) day period 
following the occurrence of such damage by giving written notice to Lessee of 
Lessor's election to do so within ten (10) days after the expiration of the 
Exercise Period, notwithstanding any term or provision in the grant of option 
to the contrary.

   9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

       (a) in the event of damage described in Paragraph 9.2 (Partial 
Damage-Insured), whether or not Lessor or Lessee repairs or restores the 
Premises, the Base Rent, Real Property Taxes, insurance premiums, and other 
charges, if any, payable by Lessee hereunder for the period during which such 
damage, its repair or the restoration continues (not to exceed the period for 
which rental value insurance is required under Paragraph 8.3(b)), shall be 
abated in proportion to the degree to which Lessee's use of the Premises is 
impaired. Except for abatement of Base Rent, Real Property Taxes, insurance 
premiums, and other charges, if any, as aforesaid, all other obligations of 
Lessee hereunder shall be performed by Lessee, and Lessee shall have no claim 
against Lessor for any damage suffered by reason for any such repair or 
restoration.

       (b) if Lessor shall be obligated to repair or restore the Premises 
under the provisions of this Paragraph 9 and shall not commence, in a 
substantial and meaningful way, the repair or restoration of the Premises 
within ninety (90) days after such obligation shall accrue, Lessee may, at 
any time prior to the commencement of such repair or restoration, give written 
notice to Lessor and to any Lenders of which Lessee has actual notice of 
Lessee's election to terminate this Lease on a date not less than sixty (60) 
days following the giving of such notice. If lessee gives such notice to 
Lessor and such Lenders and such repair or restoration is not commenced 
within thirty (30) days after receipt of such notice, this Lease shall 
terminate as of the date specified in said notice. If Lessor or a Lender 
commences the repair or restoration of the Premises within thirty (30) days 
after receipt of such notice, this Lease shall continue in full force and 
effect. "Commence" as used in this Paragraph shall mean either the 
unconditional authorization of the preparation of the required plans, or the 
beginning of the actual work on the Premises, whichever first occurs.

   9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition 
occurs, unless Lessee is legally responsible therefor (in which case Lessee 
shall make the investigation and remediation thereof required by Applicable Law 
and this Lease shall continue in full force and effect, but subject to 
Lessor's rights under Paragraph 13), Lessor may at Lessor's option either (i) 
investigate and remediate such Hazardous Substance Condition, if required, as 
soon as reasonably possible at Lessor's expense, in which event this Lease 
shall continue in full force and effect, or (ii) if the estimated cost to 
investigate and remediate such condition exceeds twelve (12) times the then 
monthly Base Rent or $100,000, whichever is greater, give written notice to 
Lessee within thirty (30) days after receipt by Lessor of knowledge of the 
occurrence of such Hazardous Substance Condition of Lessor's desire to 
terminate this Lease. Lessee shall have the right within ten (10) days after 
the receipt of such notice to give written notice to Lessor of Lessee's 
commitment to pay for the investigation and remediation of such Hazardous 
Substance Condition totally at Lessee's expense and without reimbursement from 
Lessor except to the extent of any amount equal to twelve (12) times the then 
monthly Base Rent or $100,000, whichever is greater. Lessee shall provide 
Lessor with the funds required of Lessee or satisfactory assurance thereof 
within thirty (30) days following Lessee's said commitment. In such event 
this Lease shall continue in full force and effect and Lessor shall proceed to 
make such investigation and remediation as soon as reasonably possible and 
the required funds are available. If Lessee does not give such notice and 
provide the required funds or assurance thereof within the times specified 
above, this Lease shall terminate as of the date specified in Lessor's notice 
of termination. If a Hazardous Substance Condition occurs for which Lessee is 
not legally responsible, there shall be abatement of Lessee's obligations 
under this Lease to the same extent as provided in Paragraph 9.6(a) for a 
period of not to exceed twelve months.

   9.8 TERMINATION--ADVANCE PAYMENTS. Upon termination of this Lease pursuant 
to this Paragraph 9, an equitable adjustment shall be made concerning advance 
Base Rent and any other advance payments made by Lessee to Lessor. Lessor 
shall, in addition, return to Lessee so much of Lessee's Security Deposit as 
has not been, or is not then required to be, used by Lessor under the terms 
of this Lease.

   9.9 WAIVE STATUTE. Lessor and Lessee agree that the terms of this Lease 
shall govern the effect of any damage to or destruction of the Premises with 
respect to the termination of this Lease and hereby waive the provisions of 
any present or future statute to the extent inconsistent herewith.

10. REAL PROPERTY TAXES.

   10.1 (A) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes, as 
defined in Paragraph 10.2, applicable to the Premises during the term of this 
Lease. Subject to Paragraph 10.1(b), as such payments shall be made at least 
ten (10) days prior to the delinquency date of the applicable installment. 
Lessee shall promptly furnish Lessor with satisfactory evidence that such 
taxes have been paid. If any such taxes to be paid by Lessee shall cover any 
period of time prior to or after the expiration or earlier termination of the 
term hereof, Lessee's share of such taxes shall be equitably prorated to cover 
only the period of time within the tax fiscal year this Lease is in effect, 
and Lessor shall reimburse Lessee for any overpayment after such proration. If 
Lessee shall fail to pay any Real Property Taxes required by this Lease to be 
paid by Lessee, Lessor shall have the right to pay the same, and Lessee shall 
reimburse Lessor therefor upon demand.

       (b) Advance Payment. In order to insure payment when due and before 
delinquency of any or all Real Property Taxes, Lessor reserves the right, at 
Lessor's option, to estimate the current Real Property Taxes applicable to the 
Premises, and to require such current year's Real Property Taxes to be paid in 
advance to Lessor by Lessee, either: (i) in a lump sum amount equal to the 
installment due, at least twenty (20) days prior to the applicable 
delinquency date, or (ii) monthly in advance with the payment of the Base 
Rent. If Lessor elects to require payment monthly in advance, the monthly 
payment shall be that equal monthly amount which, over the number of months 
remaining before the month in which the applicable tax installment would 
become delinquent (and without interest thereon), would provide a fund large 
enough to fully discharge before delinquency the estimated installment of 
taxes to be paid. When the actual amount of the applicable tax bill is known, 
the amount of such equal monthly advance payment shall be adjusted as 
required to provide the fund needed to pay the applicable taxes before 
delinquency. If the amounts paid to Lessor by Lessee under the provisions of 
this Paragraph are insufficient to discharge the obligations of Lessee to pay 
such Real Property Taxes as the same become due, Lessee shall pay to 
Lessor, upon Lessor's demand, such additional sums as are necessary to pay 
such obligations. All moneys paid to Lessor under this Paragraph may be 
intermingled with other moneys of Lessor and shall not bear interest. In the 
event of a Breach by Lessee in the performance of the obligations of Lessee 
under this Lease, then any balance of funds paid to Lessor under the 
provisions of this Paragraph may, subject to proration as provided in 
Paragraph 10.1(a), at the option of Lessor, be treated as an additional 
Security Deposit under Paragraph 5.

   10.2 DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term "Real 
Property Taxes" shall include any form of real estate tax or assessment, 
general, special, ordinary or extraordinary, and any license fee, commercial 
rental tax, improvement bond or bonds, levy or tax (other than inheritance, 
personal income or estate taxes) imposed upon the Premises by any authority 
having the direct or indirect power to tax, including any city, state or 
federal government, or any school, agricultural, sanitary, fire, street, 
drainage or other improvement district thereof, levied against any legal or 
equitable interest of Lessor in the Premises or in the real property of which 
the Premises are a part, Lessor's right to rent or other income therefrom, 
and/or Lessor's business of leasing the Premises. The term "REAL PROPERTY 
TAXES" shall also include any tax, fee, levy, assessment or charge, or any 
increase therein, imposed by reason of events occurring, or changes in 
applicable law taking effect, during the term of this Lease, including but 
not limited to a change in the ownership of the Premises or in the 
improvements thereon, the execution of this Lease, or any modification, 
amendment or transfer thereof, and whether or not contemplated by the Parties.

   10.3 JOINT ASSESSMENT. If the Premises are not separately assessed, 
Lessee's liability shall be an equitable proportion of the Real Property 
Taxes for all of the land and improvements included within the tax parcel 
assessed, such proportion to be determined by Lessor from the respective 
valuations assigned in the assessor's work sheets or such other information 
as may be reasonably available. Lessor's reasonable determination thereof, in 
good faith, shall be conclusive.



   10.4 PERSONAL PROPERTY TAXES. Lessee shall pay prior to delinquency all 
taxes assessed against and levied upon Lessee Owned Alterations, Utility 
Installations, Trade Fixtures, furnishings, equipment and all personal 
property of Lessee contained in the Premises or elsewhere. When possible, 
Lessee shall cause its Trade Fixtures, furnishings, equipment and all other 
personal property to be assessed and billed separately from the real property 
of Lessor. If any of Lessee's said personal property shall be assessed with 
Lessor's real property, Lessee shall pay Lessor the taxes attributable to 
Lessee within ten (10) days after receipt of a written statement setting 
forth the taxes applicable to Lessee's property or, at Lessor's option, as 
provided in Paragraph 10.1(b).

11. UTILITIES. Lessee 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. If any such services are not 
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be 
determined by Lessor, of all charges jointly metered with other premises.

12. ASSIGNMENT AND SUBLETTING.

   12.1 LESSOR'S CONSENT REQUIRED.

        (a) Lessee shall not voluntarily or by operation of law assign, 
transfer, mortgage or otherwise transfer or encumber (collectively, 
"ASSIGNMENT") or sublet all or any part of Lessee's interest in this Lease or 
in the Premises without Lessor's prior written consent given under and 
subject to the terms of Paragraph 36.

        (b) A change in the control of Lessee shall constitute an assignment 
requiring Lessor's consent. The transfer, on a cumulative basis, of 
twenty-five percent (25%) or more of the voting control of Lessee shall 
constitute a change in control for this purpose.

        (c) The involvement of Lessee or its assets in any transaction, or 
series of transactions (by way of merger, sale, acquisition, financing, 
refinancing, transfer, leveraged buy-out or otherwise), whether or not a 
formal assignment or hypothecation of this Lease or Lessee's assets occurs, 
which results or will result in a reduction of the Net Worth of Lessee, as 
hereinafter defined, by an amount equal to or greater than twenty-five percent 
(25%) of such Net Worth of Lessee as it was represented to Lessor at the time 
of the execution by Lessor of this Lease or at the time of the most recent 
assignment to which Lessor has consented, or as it exists immediately prior 
to said transaction or transactions constituting such reduction, at whichever 
time said Net Worth of Lessee was or is greater, shall be considered an 
assignment of this Lease by Lessee to which Lessor may reasonably withhold 
its consent. "NET WORTH OF LESSEE" for the purposes of this Lease shall be 
the net worth of Lessee (excluding any guarantors) established under 
generally accepted accounting principles consistently applied.

        (d) An assignment or subletting of Lessee's interest in this Lease 
without Lessor's specific prior written consent shall, at Lessor's option, be 
a Default curable after notice per paragraph 13.1(c), or a noncurable Breach 
without the necessity of any notice and grace period. If Lessor elects to 
treat such unconsented to assignment or subletting as a noncurable Breach, 
Lessor shall have the right to either: (i) terminate this Lease, or (ii) upon 
thirty (30) days written notice ("LESSOR'S NOTICE"), increase the monthly 
Base Rent to fair market rental value or one hundred ten percent (110%) of 
the Base Rent then in effect, whichever is greater. Pending determination of 
the new fair market rental value, if disputed by Lessee, Lessee shall pay the 
amount set forth in Lessor's Notice, with any overpayment credited against 
the next installment(s) of Base Rent coming due, and any underpayment for the 
period retroactively to the effective date of the adjustment being due and 
payable immediately upon the determination thereof. Further, in the event of 
such Breach and market value adjustment, (i) the purchase price of any option 
to purchase the Premises held by Lessee shall be subject to similar 
adjustment to the then fair market value (without the Lease being considered 
an encumbrance or any deduction for depreciation or obsolescence, and 
considering the Premises at its highest and best use and in good condition), 
or one hundred ten percent (110%) of the price previously in effect, 
whichever is greater, (ii) any index-oriented rental or price adjustment 
formulas contained in this Lease shall be adjusted to require that the base 
index be determined with reference to the index applicable to the time of 
such adjustment, and (iii) any fixed rental adjustments scheduled during the 
remainder of the Lease term shall be increased in the same ratio as the new 
market rental bears to the Base Rent in effect immediately prior to the 
market value adjustment.

   12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

        (a) Regardless of Lessor's consent, any assignment or subletting 
shall not: (i) be effective without the express written assumption by such 
assignee or sublease of the obligations of Lessee under this Lease, (ii) 
release Lessee of any obligations hereunder, or (iii) after the primary 
liability of Lessee for the payment of Base Rent and other sums due Lessor 
hereunder or for the performance of any other obligations to be performed by 
Lessee under this Lease.

        (b) Lessor may accept any rent or performance of Lessee's obligations 
from any person other than Lessee pending approval or disapproval of an 
assignment. Neither a delay in the approval or disapproval of such assignment 
nor the acceptance of any rent or performance shall constitute a waiver or 
estoppel of Lessor's right to exercise its remedies for the Default or 
Breach by Lessee of any of the terms, covenants or conditions of the Lease.

        (c) The consent of Lessor to any assignment or subletting shall not 
constitute a consent to any subsequent assignment or subletting by Lessee or 
to any subsequent or successive assignment or subletting by the sublessee. 
However, Lessor may consent to subsequent sublettings and assignments of the 
sublease or any amendments or modifications thereto without notifying Lessee 
or anyone else liable on the Lease or sublease and without obtaining their 
consent, and such action shall not relieve such persons from liability under 
this Lease or sublease.

        (d) In the event of any Default or Breach of Lessee's obligations 
under this Lease, Lessor may proceed directly against Lessee, any Guarantors 
or any one else responsible for the performance of the Lessee's obligations 
under this Lease, including the sublessee, without first exhausting Lessor's 
remedies against any other person or entity responsible therefor to Lessor, 
or any security held by Lessor or Lessee.

        (e) Each request for consent to an assignment or subletting shall be 
in writing, accompanied by information relevant to Lessor's determination as 
to the financial and operational responsibility and appropriateness of the 
proposed assignee or sublessee, including but not limited to the intended use 
and/or required modification of the Premises, if any, together with a 
non-refundable deposit of $1,000 or ten percent (10%) of the current monthly 
Base Rent, whichever is greater, as reasonable consideration for Lessor's 
considering and processing the request for consent Lessee agrees to provide 
Lessor with such other or additional information and/or documentation as may 
be reasonably requested by Lessor.

        (f) Any assignee of, or sublessee under, this Lease shall, by reason 
of accepting such assignment or entering into such sublease, be deemed, for 
the benefit of the Lessor, to have assumed and agreed to conform and comply 
with each and every term, covenant, condition and obligation herein to be 
observed or performed by Lessee during the term of said assignment or 
sublease, other than such obligations as are contrary to or inconsistent with 
provisions of an assignment or sublease to which Lessor has specifically 
consented in writing.

        (g) The occurrence of a transaction described in Paragraph 12.1(c) 
shall give Lessor the right (but not the obligation) to require that the 
Security Deposit be increased to an amount equal to six (6) times the then 
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the 
amount required to establish such Security Deposit a condition to Lessor's 
consent to such transaction.

        (h) Lessor, as a condition to giving its consent to any assignment or 
subletting, may require that the amount and adjustment structure of the rent 
payable under this Lease be adjusted to what is then the market value and/or 
adjustment structure for property similar to the Premises as then constituted 

   12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The 
following terms and conditions shall apply to any subletting by Lessee of all 
or any part of the Premises and shall be deemed included in all subleases 
under this Lease whether or not expressly incorporated therein:

        (a) Lessee hereby assigns and transfers to Lessor all of Lessee's 
interest in all rentals and income arising from any sublease of all or a 
portion of the Premises heretofore or hereafter made by Lessee, and Lessor may 
collect such rent and income and apply same toward Lessee's obligations under 
this Lease: provided, however, that until a Breach (as defined in Paragraph 
13.1) shall occur in the performance of Lessee's obligations under this 
Lease. Lessee may, except as otherwise provided in this Lease, receive, 
collect and enjoy the rents accruing under such sublease. Lessor shall not, 
by reason of this or any other assignment of such sublease to Lessor, nor by 
reason of the collection of the rents from a sublessee, be deemed liable to 
the sublessee for any failure of Lessee to perform and comply with any of the 
Lessee's obligations to such sublessee under such sublease. Lessee hereby 
irrevocably authorizes and directs any such sublessee, upon receipt of a 
written notice from Lessor stating that a Breach exists in the performance of 
the Lessee's obligations under this Lease, to pay to Lessor the rents and 
other charges due and to become due under the sublease. Sublessee shall rely 
upon any such statement and request from Lessor and shall 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 or Breaches of such sublessor under such 
sublease.

        (c) Any matter or thing requiring the consent of the sublessor under 
a sublease shall also require the consent of Lessor herein.

        (d) No sublessee shall further assign or sublet all or any part of 
the Premises without Lessor's prior written consent.

        (e) Lessor shall deliver a copy of any notice of Default or Breach by 
Lessee to the sublessee, who shall have the right to cure the Default of 
Lessee within the grace period, if any, specified in such notice. The 
sublessee shall have a right of reimbursement and offset from and against 
Lessee for any such Default cured by the sublessee.

13. DEFAULT; BREACH; REMEDIES.

   13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is 
consulted by Lessor in connection with a Lessee Default or Breach (as 
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence 
for legal services and costs in the preparation and Service of a notice of 
Default and that Lessor may include the cost of such Services and cost in 
said notice as rent due and payable to cure said Default. A "Default" is 
defined as a failure by the Lessee to observe, comply with or perform any of 
the items, covenants, conditions or rules applicable to Lessee under this 
Lease. A "Breach" is defined as the occurrence of any one or more of the 
following Defaults, and, where a grace period for cure after notice is 
specified herein, the failure by Lessee to cure such Default prior to the 
expiration of the applicable grace period, and shall entitle Lessor to pursue 
the remedies set forth in Paragraph 13.2 and/or 13.3:

        (a) The vacating of the Premises without the intention to reoccupy 
same, or the abandonment of the Premises.





         (b) Except as expressly otherwise provided in this Lease, the 
failure by Lessee to make any payment of Base Rent or any other monetary 
payment required to be made by Lessee hereunder, whether to Lessor or to a 
third party, as and when due, the failure by Lessee to provide Lessor with 
reasonable evidence of insurance or surety bond required under this Lease, or 
the failure of Lessee to fulfill any obligation under this Lease which 
endangers and threatens life or property, where such failure continues for a 
period of three (3) days following written notice thereof by or on behalf of 
Lessor to Lessee.

         (c) Except as expressly otherwise provided in this Lease, the 
failure by Lessee to provide Lessor with reasonable written evidence (in duly 
executed original form, if applicable) of (i) compliance with applicable law 
per Paragraph 6.3, (ii) the inspection, maintenance and service contract 
required under Paragraph 7.1(b), (iii) the recission of an unauthorized 
assignment or subletting per Paragraph 12.1(b), (iv) a Tenancy Statement of 
Paragraphs 16 or 37, (v) the subordination or non-subordination of this Lease 
per Paragraph 30, (vi) the guaranty of the performance of Lessee's obligations 
under this Lease if required under Paragraphs 1.11 and 37, (vii) the execution 
of any document requested under Paragraph 42 leasements or (viii) any other 
documentation or information which Lessor may reasonably require of Lessee 
under the terms of this Lease, where any such failure continues for a period 
of ten (10) days following written notice by or on behalf of Lessor to Lessee.

         (d) A Default by Lessee as to the terms, covenants, conditions or 
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof 
that are to be observed, complied with or performed by Lessee, other than 
those described in subparagraphs (a), (b) or (c), above, where such Default 
continues for a period of thirty (30) days after written notice thereof by or 
on behalf of Lessor to Lessee; provided, however, that if the nature of 
Lessee Default is such that more than thirty (30) days are reasonably 
required for its cure, then it shall not be deemed to be a Breach of this 
Lease by Lessor if Lessee commences such cure within said thirty (30) days 
are reasonably required for its cure, then it shall not be deemed to be a 
Breach of this Lease by Lessor if Lessee commences such cure within said 
thirty (30) day period and thereafter diligently prosecutes such cure to 
completion.

         (e) The occurrence of any of the following events: (i) The making by 
Lessee of any general arrangement or assignment for the benefit of creditors 
(ii) Lessee's becoming a "debtor" as defined in 11 U.S.C. Section 101 or any 
successor statute thereto (unless, in the case of a petition filed against 
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment 
of a trustee or receiver to take possession of substantially all of Lessee's 
assets located at the Premises or of Lessee's interest in this Lease, where 
possession is not restored to Leases within thirty (30) days; or (iv) the 
attachment, execution of other judicial seizure of substantially all of 
Lessee's assets located at the Premises or of Lessee's interest in this 
Lease, where such seizure is not discharged within thirty (30) days; 
provided, however. In the event that any provision of this subparagraph (e) 
is contrary to any applicable law.  Such provision shall be of no force or 
effect, and not affect the validity of the remaining provisions.

         (f) The discovery by Lessor that any financial statement given to 
Lessor by Lessee or any Guarantor of Lessee's obligations hereunder is 
materially false.

         (g) If the performance of Lessee's obligations under this Lease is 
guaranteed: (i) the death of a guarantor, (ii) the termination of a 
guarantor's liability with respect to this Lease other than in accordance 
with the terms of such guaranty, (iii) a guarantor's becoming insolvent or 
the subject of a bankruptcy filing, (iv) a guarantor's refusal to honor the 
guaranty, or (v) a guarantor's breach of the guaranty obligation on an 
anticipatory breach basis and Lessee's failure, within sixty (60) days 
following written notice by or on behalf of Lessor to Lessee of any such 
event, 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.

    13.2 REMEDIES. If Lessee fails to perform any affirmative duty or 
obligation of Lessee under this Lease, within ten (10) days after written 
notice to Lessee (or in case of an emergency, without notice), Lessor may at 
its option (but without obligation to do so), perform such duty or obligation 
on Lessee's behalf, including but not limited to the obtaining of reasonably 
required bonds, insurance policies, or governmental licenses, permits or 
approvals. The costs and expenses of any such performance by Lessor shall be 
due and payable by Lessee to Lessor upon invoice therefor. If any check given 
to Lessor by Lessee shall not be honored by the bank upon which it is drawn, 
Lessor, at its option, may require all future payments to be made under this 
Lease by Lessee to be made only by cashier's check. In the event of a Breach 
of this Lease by Lessee, as defined in Paragraph 13.1, with or without 
further notice or demand, and without limiting Lessor in the exercise of any 
right or remedy which Lessor may have by reason of such Breach, Lessor may:

         (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, including 
necessary renovation and alteration of the Premises, 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 time 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 13.1(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 1951.4) 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 on 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.

    13.3 INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor for 
free or abated rent or other charges applicable to the Premises, or for the 
giving or paying by Lessor to or for Lessee of any cash or other bonus, 
inducement or consideration for Lessee's entering into this Lease, all of 
which concessions are hereinafter referred to as "Inducement Provisions," 
shall be deemed conditioned upon Lessee's full and faithful performance at 
all of the terms, covenants and conditions of this Lease to be performed or 
observed by Lessee during the term hereof as the same may be extended. Upon 
the occurrence of a Breach of this Lease by Lessee, as defined in Paragraph 
13.1, any such Inducement Provision shall automatically be deemed deleted 
from this Lease and of no further force or effect, and any rent, other 
charge, bonus, inducement or consideration theretofore abated, given or paid 
by Lessor under such an Inducement Provision shall be immediately due and 
payable by Lessee to Lessor, and recoverable by Lessor as additional rent due 
under this Lease, notwithstanding any subsequent cure of said Breach by 
Lessee. The acceptance by Lessor of rent or the cure of the Breach which 
initiated the operation of this Paragraph shall not be deemed a waiver by 
Lessor of the provisions of this Paragraph unless specifically so stated in 
writing by Lessor at the time of such acceptance.

     13.4 LATE CHARGES. Lessee hereby acknowledges that late 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 five 
(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 4.1 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 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 threat of the 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 twenty-five percent 
(25%) of the land area not occupied by any building, 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 building 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 shall be entitled to any 
compensation, separately awarded to Lessee for Lessee's relocation expenses 
and/or damages received, over and above the legal and other expenses incurred 
by Lessor in the 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 therefor by the condemning authority. Lessee shall be 
responsible for the payment of any amount in excess of such net severance 
damages required to complete such repair.

16. TENANCY STATEMENT.
    16.1 Each Party (as "Responding Party") shall within ten (10) days after 
written notice from the other Party (the "Requesting Party") execute, 
acknowledge and deliver to the Requesting Party a statement in writing in 
form similar to the then most current "Tenancy Statement" form published by 
the American Industrial Real Estate Association, plus such additional 
information, confirmation and/or statements as may be reasonably requested by 
the Requesting Party.

    16.2 If Lessor desires to finance, refinance, or sell the Premises, any 
part thereof, or the building of which the Premises are a part, Lessee and as 
Guarantors of Lessee's performance hereunder shall deliver to any potential 
lender or purchaser designated by Lessor such financial statements of Leases 
and such Guarantors as may be reasonably required by such lender or 
purchaser, including but not limited to Lessee's financial statements for the 
past three (3) years. All such financial statements shall be received by 
Lessor and such lender or purchaser in confidence and shall be used only for 
the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean the owner 
or owners at the time in question of the fee title to the Premises, or, if 
this is a sublease, of the lessee's interest in the prior lease. In the event 
of a transfer of Lessor's state or interest in the Premises or in this Lease, 
Lessor shall deliver to the transferee or assignee (in cash or by credit) any 
unused Security Deposit held by Lessor at the time of such transfer or 
assignment. Except as provided in Paragraph 16, upon such transfer or 
assignment and delivery of the Security Deposit, as aforesaid, the prior 
Lessor shall be relieved 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.

19. INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor 
hereunder, 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 
thirty-first (31st) day after it was due at the rate of 12% per annum, but 
not exceeding the maximum rate allowed by laws, in addition to the late 
charge provided for in Paragraph 13.4.

20. TIME OF ESSENCE. Time is of the essence with respect to the performance 
of all obligations to be performed or observed by the Parties under this 
Lease.

21. RENT DEFINED. All monetary obligations of Lessee to Lessor under the 
terms of this Lease are deemed to be rent.

22. NO PRIOR OR OTHER AGREEMENTS, BROKER DISCLAIMER. This Lease 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. Lessor and Lessee each represents and warrants to the Broker's 
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 Lease and as to the 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.

23. NOTICES.
    23.1  All notices required or permitted by this Lease shall be in writing 
and may be delivered in person (by hand or by messenger or courier service) 
or may be sent by regular, certified or registered mail or U.S. Postal 
Service Express Mall, with postage prepaid, or by facsimile transmission, and 
shall be deemed sufficiently given if served in a manner specified in this 
Paragraph 23. The addresses noted adjacent to a Party's signature on this 
Lease shall be that Party's address for delivery or mailing of notice 
purposes. Either Party may by written notice to the other specify a different 
address for notice purposes, except that upon Lessee's taking possession of 
the Premises, the Premises shall constitute Lessee's address for the purpose 
of mailing or delivering notices to Lessee. A copy of all notices required or 
permitted to be given to Lessor hereunder shall be concurrently transmitted 
to such party or parties at such addresses as Lessor may from time to time 
hereafter designate by written notice to Lessee.

    23.2  Any notice sent by registered or certified mail, return receipt 
requested shall be deemed given on the date of delivery shown on the receipt 
card, or if no delivery date is shown, the postmark thereon. If sent by 
regular mail the notice shall be deemed given forty-eight (48) hours after 
the same is addressed as required herein and mailed with postage prepaid. 
Notices delivered by United States Express Mail or overnight courier that 
guarantees next day delivery shall be deemed given twenty-four (24) hours 
after delivery of the same to the United States Postal Service or courier. If 
any notice is transmitted by facsimile transmission or similar means, the 
same shall be deemed served or delivered upon telephone confirmation of 
receipt of the transmission thereof, provided a copy is also delivered via 
delivery or mail. If notice is received on a Sunday or legal holiday, it 
shall be deemed received on the next business day.

24.  WAIVERS. No waiver by Lessor of the Default or Breach of any term, 
covenant or condition hereof by Lessee, shall be deemed a waiver of any other 
term, covenant or condition hereof, or of any subsequent Default or Breach by 
Lessee of the same or of any other term, covenant or condition hereof. 
Lessor's consent to, or approval of, any act shall not be deemed to render 
unnecessary the obtaining of Lessor's consent to, or approval of, any 
subsequent or similar act by Lessee, or be construed as the basis of an 
estoppel to enforce the provision or provisions of this Lease requiring such 
consent. Regardless of Lessor's knowledge of a Default or Breach at the time 
of accepting rent, the acceptance of rent by Lessor shall not be a waiver of 
any preceding Default or Breach by Lessee of any provision hereof, other than 
the failure of Lessee to pay the particular rent so accepted. Any payment 
given Lessor by Lessee may be accepted by Lessor on account of moneys or 
damages due Lessor, notwithstanding any qualifying statements or conditions 
made by Lessee in connection therewith, which such statements and/or 
conditions shall be of no force or effect whatsoever unless specifically 
agreed to in writing by Lessor at or before the time of deposit of such 
payment.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a short form memorandum of this 
Lease for recording purposes. The Party requesting recordation shall be 
responsible for payment of any fees or taxes applicable thereto.

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the 
Premises or any part thereof beyond the expiration or earlier termination of 
this Lease.

27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed 
exclusive but shall, wherever possible, be cumulative with all other remedies 
at law or in equity.

                                     PAGE 5



28. COVENANTS AND CONDITIONS. All provisions of this Lease to be observed or 
performed by Lessee are both covenants and conditions.

29. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the 
parties, their personal representatives, successors and assigns and be 
governed by the laws of the State in which the Premises are located. Any 
litigation between the Parties hereto concerning this Lease shall be 
initiated in the county in which the Premises are located.

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

    30.1 SUBORDINATION. This Lease and any Option granted hereby shall be 
subject and subordinate to any ground lease, mortgage, deed of trust, or 
other hypothecation or security device (collectively, "Security Device"), now 
or hereafter placed by Lessor upon the real property of which the Premises 
are part to any and all advances made on the security thereof, and to all 
renewals, modifications, consolidations, replacements and extensions there 
Lessee agrees that the Lenders holding any such Security Device shall have no 
duty, liability or obligation to perform any of the obligations of Lessee 
under this Lease, but that in the event of Lessor's default with respect to 
any such obligation, Lessee will give any Lender whose name and address has 
been furnished Lessee in writing for such purpose notice of Lessor's default 
and allow such Lender thirty (30) days following receipt of such notice of 
the cure of said default before invoking any remedies Lessee may have by 
reason thereof. If any Lender shall elect to have this Lease and/or any 
Option granted hereby superior to the lien of its Security Device and shall 
give written notice thereof to Lessee, this Lease and such Options shall be 
deemed prior to such Security Device, notwithstanding the relative dates of 
the documentation or recordation thereof.

    30.2 ATTORNMENT. Subject to the non-disturbance provisions of Paragraph 
30.3, Lessee agrees to attorn to a Lender or any other party who acquires 
ownership of the Premises by reason of a foreclosure of a Security Device, 
and that in the event of such foreclosure, such new owner shall not: (i) be 
liable for any act or omission of any prior lessor or with respect to events 
occurring prior to acquisition of ownership, (ii) be subject to any offsets 
or defense which Lessee might have against any prior lessor, or (iii) be 
bound by prepayment of more than one month's rent.

    30.3 NON-DISTURBANCE. With respect to Security Devices entered into by 
Lessor after the execution of this Lease, Lessee's subordination of this 
Lease shall be subject to receiving assurance (a "non-disturbance agreement") 
from the Lender that Lessee's possession and this Lease, including any option 
to extend the term hereof, will not be disturbed so long as Lessee is not in 
Breach hereof and attorn to the record owner of the Premises.

    30.4 SELF-EXECUTING. The agreements contained in this Paragraph 30 shall 
be effective without the execution of any further documents; provided 
however, that, upon written request from Lessor or a Lender in connection 
with a sale, financing or refinancing of the Premises, Lessee and Lessor 
shall execute such further writings as may be reasonably required to 
separately document any such subordination or non-subordination, attornment 
and/or non-disturbance agreement as is provided for herein.

31. ATTORNEY'S FEES. If any Party or Broker brings an action or proceeding to 
enforce the terms hereof or declare rights hereunder, the Prevailing Party 
(as hereafter defined) or Broker in any such proceeding, action, or appeal 
thereon, shall be entitled to reasonable attorney's 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 attorney's fee award shall not be 
computed in accordance with any court fee schedule, but shall be such as to 
fully reimburse all attorney's fees reasonably incurred. Lessor shall be 
entitled to attorney's 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.

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents 
shall have the right to enter the Premises at any time. In the case of an 
emergency, and otherwise at reasonable times for the purpose of showing the 
same to prospective purchasers, lenders, or lessees, and making such 
alterations, repairs, improvements or additions to the Premises or to the 
building of which they are a part, as Lessor may reasonably deem necessary. 
Lessor may at any time place on or about the Premises or building any 
ordinary "For Sale" signs and Lessor may at any time during the last one 
hundred twenty (120) days of the term hereof place on or about the Premises 
any ordinary "For Lease" signs. All such activities of Lessor shall be 
without abatement of rent or liablilty to Lessee.

33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either 
voluntarily or involuntarily, any auction upon the Premises without first 
having obtained Lessor's prior written consent. Notwithstanding anything to 
the contrary in this Lease, Lessor shall not be obligated to exercise any 
standard of reasonableness in determining whether to grant such consent.

34. SIGNS. Lessee shall not place any sign upon the Premises, except that 
Lessee may, with Lessor's prior written consent, install (but not on the 
roof) such signs as are reasonably required to advertise Lessee's own 
business. The installation of any sign on the Premises by or for Lessee shall 
be subject to the provisions of Paragraph 7 (Maintenance, Repairs, Utility 
Installations, Trade Fixtures and Alterations). Unless otherwise expressly 
agreed herein, Lessor reserves all rights to the use of the roof and the 
right to install, and all revenues from the installation of, such advertising 
signs on the Premises, including the roof, as do not unreasonably interfere 
with the conduct of Lessee's business.

35. TERMINATION; MERGER. Unless specifically stated otherwise in writing by 
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual 
termination or cancellation hereof, or a termination hereof by Lessor for 
Breach by Lessee shall automatically terminate any sublease or lesser estate 
on the Premises; provided however, Lessor shall, in the event of any such 
surrender, termination or cancellation, have the option to continue any one 
or all of any existing subtenancies. Lessor's failure within ten (10) days 
following any such event to make a written election to the contrary by 
written notice to the holder of any such lesser interest, shall constitute 
Lessor's election to have such event constitute the termination of such 
interest.

36. CONSENTS.

         (a) Except for Paragraph 33 hereof (Auctions) or as otherwise 
provided herein, wherever in this Lease the consent of a Party is required to 
an act by or for the other Party, such consent shall not be unreasonably 
withheld or delayed. Lessor's actual reasonable costs and expenses (including 
but not limited to architects', attorneys', engineers' or other consultant's 
fees) incurred in the consideration of, or response to, a request by Lessee 
for any Lessor consent pertaining to this Lease or the Premises, including 
but not limited to consents to an assignment, a subletting or the presence or 
use of a Hazardous Substance, practice or storage tank, shall be paid by 
Lessee to Lessor upon receipt of an invoice and supporting documentation 
therefor. Subject to Paragraph 12.2(e) (applicable to assignment or 
subletting), Lessor may, as a condition to considering any such request by 
Lessee, require that Lessee deposit with Lessor an amount of money (in 
addition to the Security Deposit held under Paragraph 8) reasonably 
calculated by Lessor to represent the cost Lessor will incur in considering 
and responding to Lessee's request. Except as otherwise provided, any unused 
portion of said deposit shall be refunded to Lessee without interest. 
Lessor's consent to any act, assignment of this Lease or subletting of the 
Premises by Lessee shall not constitute an acknowledgment that no Default or 
Breach by Lessee of this Lease exists, nor shall such consent be deemed a 
waiver of any then existing Default or Breach, except as may be otherwise 
specifically stated in writing by Lessor at the time of such consent.

         (b) All conditions to Lessor's consent authorized by this Lease are 
acknowledged by Lessee as being reasonable. The failure to specify herein any 
particular conditions to Lessor's consent shall not preclude the imposition 
by Lessor at the time of consent of such further or other conditions as are 
then reasonable with reference to the particular matter for which consent is 
being given.

37. GUARANTOR.

     37.1 If there are to be any Guarantors of this Lease per Paragraph 1.11, 
the form of the guaranty to be executed by each such Guarantor shall be in

Association, and each said Guarantor shall have the same obligations as 
Lessee under this Lease, including but not limited to the obligation to 
provide the Tenancy Statement and Information called for by Paragraph 16.

such Guarantor fails or refuses, upon reasonable request by Lessor to give;

including the authority of the Guarantor (and of the party signing on 
Guarantor's behalf) to obligate such Guarantor on said guaranty, and 
including in the case of a corporate Guarantor, a certified copy of a 
resolution of its board of directors authorizing the making of such guaranty, 
together with a certificate of incumbency showing the signatures of the 
persons authorized to sign on its behalf, (b) current financial statements of 
Guarantor as may from time to time be requested by Lessor, (c) a Tenancy 
Statement, or (d) written confirmation that the guaranty is still in effect.

terminate and be of no further force or effect, notwithstanding Lessee's due 
and timely exercise of the Option, if, after such exercise and during the

restrictions.

                                 LEASE ADDENDUM



          This LEASE ADDENDUM ("Addendum") is attached to, made a part of, 
incorporated into and amends and supplements that certain Standard 
Industrial/Commercial Single-Tenant Lease - Net (the "Lease") entered into as 
of April 18, 1997 by and between THE CARTER FAMILY INVESTMENT PARTNERSHIP, 
L.P., a California limited partnership ("Lessor"), and NATIONAL TELEPHONE & 
COMMUNICATIONS, INC., a Delaware corporation ("Lessee").  Lessor and Lessee 
agree that notwithstanding anything contained in the Lease to the contrary, 
the provisions set forth in this Addendum will be deemed to be a part of the 
Lease and will supersede any contrary provision in the Lease and prevail and 
control for all purposes.  It is the intention of the parties that the use of 
this Addendum will eliminate for the most part the need to strike through and 
interlineate portions of the Lease in order to reflect the changes to the 
Lease desired by the parties as set forth in this Addendum.  All references 
in the Lease and in this Addendum to "Lease" are to be construed to mean the 
Lease as amended and supplemented by this Addendum.  All terms used in this 
Addendum, unless specifically defined in this Addendum, have the same 
meanings as the terms used in the Lease.

          Item 1.  Paragraph 3.1.  OPTION TO EXTEND TERM.

               (a)  Subject to the terms of this Paragraph 3.1, Lessor hereby 
grants to Lessee seven (7) options ("Extension Options") to extend the Term 
of the Lease for consecutive additional periods of five (5) years each 
("Option Terms"), on the same terms, covenants and conditions as provided for 
in the Lease for the initial Term, except that Base Rent during the Option 
Terms shall be as set forth in this Paragraph 3.1.  Lessee shall exercise 
each Extension Option, if at all, by providing Lessor with not less than 
twenty-four (24) months written notice prior to the expiration of the 
Original Term with respect to the first Extension Option and not less than 
eighteen (18) months written notice prior to the expiration of any successive 
Option Term. 

               (b)  Base Rent shall be increased by cost of living increases 
applied to the sum of Twenty-Five Thousand Dollars ($25,000), plus any 
previous cost of living adjustments to such sum made as a result of the 
exercise of any previous options.  Such increase shall occur on the first day 
of each Option Term  ("Adjustment Date")in accordance with percentage 
increases, if any, in the Consumer Price Index--Urban Consumers (Los 
Angeles-Anaheim-Riverside CA area; Base 1982-84=100) ("Index"), as published 
by the United States Department of Labor, Bureau of Labor Statistics 
("Bureau").  The Index for the month which is four (4) months prior to the 
Adjustment Date ("Comparison Month") shall be compared to the Index which is 
four (4) months prior to the Commencement Date ("Base Index") and the 
Twenty-Five Thousand Dollars ($25,000) shall be increased upon the Adjustment 
Date in accordance with the percentage increase, if any, between such 
indexes.  Should the Bureau discontinue the publication of the Index, or 
publish the same less frequently, or alter the same in some other manner, 
Lessor, in its discretion will adopt a substitute index or procedure which 
reasonably reflects and  monitors consumer prices.  Under no circumstances 
will this sum be less than the amount of this sum during the prior five (5) 
year period.

          Item 3.  Paragraph 6.3.  LESSEE'S COMPLIANCE WITH LAW. 
Notwithstanding anything to the contrary contained in Paragraph 6.3 or 
elsewhere in the Lease, Lessee's obligation to comply with "Applicable Law" 
with respect to industrial hygiene shall also not apply to any conditions at 
the Premises existing prior to Lessee's occupancy thereof and shall be 
limited to industrial hygiene matters relating to Lessee's operations from 
the Premises.  Lessee's obligations with respect to environmental conditions 
and the use, generation, manufacture, production, installation, maintenance, 
removal, transportation, storage, spill or release of Hazardous Substances 
shall also not apply to any conditions at the Premises existing prior to 
Lessee's occupancy thereof and shall be limited to such matters as are caused 
after Lessee's occupancy of the Premises.

hereto and to deduct same from the payment of Base Rent to Lessor.  Further, 
in the event of any default by Lessor under the Loan, Lessee shall have the 
right to cure such default by making a payment directly to the Lender, or 
correcting the default alleged by the Lender under the Loan and to thereafter 
offset the amount of the curative payment or the sums expended by Lessee in 
connection with the curing of Lessor's default against Lessee's obligations 
with respect Base Rent under this Lease.  Lessee shall have the further right 
to offset any default in payment by Lessor with respect to the Lessee's Note 
against Lessee's obligations with respect to Base Rent under the Lease.

          Item 6.  Paragraph 7.3.  UTILITY INSTALLATIONS; TRADE FIXTURES; 
ALTERATIONS.  Notwithstanding anything to the contrary contained in the 
Lease, Lessee shall have the right to remove all Trade Fixtures and personal 
property upon the expiration or sooner termination of the Lease, provided 
Lessee shall repair any damage caused by such removal and shall restore the 
Premises as to the items so removed only to the condition received.  Further, 
notwithstanding anything to the contrary contained in the Lease, Lessee shall 
have the further right to develop a parking structure of four (4) stories and 
approximately 116,980 square feet, and additional office space of 
approximately 56,721 square feet, in accordance with the other requirements 
of this Lease and Lessor shall not unreasonably withhold consent to any 
aspect of the development so long as such development is of first quality in 
substantial conformity with renderings and models presented to Lessor.  The 
rights of Lessee to develop such projects on the Premises, in accordance with 
this paragraph, shall terminate for any improvements if physical construction 
has not started within three (3) years of the commencement of this Lease and 
not completed within four (4) years, provided that Lessee has exercised the 
option to extend this Lease.  If Lessee has not exercised the option to 
extend, all construction must be completed before three (3) years after 
commencement of this Lease.  

          Item 7.  Paragraph 7.4(a).  OWNERSHIP.  The second and third

anything to the contrary contained in Paragraph 7.4(c) or elsewhere in the 
Lease, Lessee shall have the right but not the obligation to remove all trade 
fixtures and personal property installed by Lessee upon the expiration of 
sooner termination of the Lease, provided Lessee shall repair any damage 
caused by such removal and shall restore the Premises as to the items so 
removed only to the condition received as of the commencement of the Lease as 
provided in the Lease and shall not otherwise have any obligation to restore 
the Premises.

          Item 9.  Paragraph 8.3(a).  PROPERTY INSURANCE - BUILDING, 
IMPROVEMENTS AND RENTAL VALUE.  Lessee shall be the Insuring Party and the 
policy of property insurance to be maintained by Lessor pursuant to Paragraph

payable to Lessee in addition to those parties named in Paragraph 8.3(a).

          Item 10.  Paragraph 8.4.  LESSEE'S PROPERTY INSURANCE. 
Notwithstanding anything to the contrary contained in Paragraph 8.4 or 
elsewhere in the Lease, Lessee's insurance for Lessee's personal property 
shall be in an amount equal to full insurable value of such property, not 
full replacement cost.

          Item 11.  Paragraph 8.7.  LESSOR'S INDEMNITY.  Notwithstanding 
anything to the contrary contained in Paragraph 8.7 or elsewhere in the 
Lease, Lessor shall indemnify, protect, defend and hold harmless Lessee and 
its agents, partners and lenders from and against any and all claims,

the contrary contained in Paragraph 13.2 or elsewhere in the Lease, Lessor 
shall not have the right to exercise its remedies unless Lessee shall fail to

best efforts to obtain such non-disturbance agreements from all beneficiaries

          contrary during the period commencing with the giving of any
          noticed Default under Paragraph 13.1 and continuing until

entirety and replaced with the following:

               "(c) All rights of Lessee under the provisions of an

          Option, if, after such exercise and during the term of this
          Lease, Lessee is in Default under this Lease, unless Lessee
          subsequently cures such Default in a manner satisfactory to
          Lessor and the Lease is reinstated in good standing by
          Lessor."

the parties hereto that the remainder of the Lease shall not be affected 
thereby, and it is also the intention of the parties to the Lease that, in
